Parameter of Anti-corrosion Carbon Brick
REBO anti-corrosion carbon bricks use high-purity calcined petroleum coke and coal tar pitch, processed with our proprietary technology for dense body, low porosity and high strength. Sintered and pressed chemical carbon bricks are our two best-selling types, both resisting strong acids in phosphoric acid tanks, acid washing equipment and pickling lines. REBO offers stable quality and fast lead time.
- Pressed Carbon Bricks: These bricks work in fully ambient conditions with no steam and no thermal cycling. Media temperature stays below 120°C. They are common in standard pickling tanks, ambient acid storage tanks, and wastewater treatment.
- Sintered Carbon Bricks: These bricks work in heated conditions. They handle steam, thermal cycling, hot acid media, fluoride corrosion, and long continuous production. These bricks are common in high-temperature reactors, phosphoric acid chemical equipment, and metallurgical pickling furnaces.

By Manufacturing Process
- Pressed carbon brick: Uses carbon powder with phenolic resin binder. High-pressure formed and low-temperature cured. No high-temperature firing. Resin coats particles and fills gaps. Fast production, standard size, smooth surface. Organic-bonded structure: simple process, low cost, quick delivery.
- Sintered carbon brick: Uses carbon aggregate with high-temperature pitch binder. Formed and fired in a closed kiln above 1300°C. Pitch turns fully into carbon. Particles form integrated carbon bonds. Pure inorganic carbon structure: complex process, high energy use, long cycle. High-end industrial grade.
Typed By Material Type
- Standard anti-corrosion carbon brick uses high-purity calcined petroleum coke. It is fired at high temperature and vacuum resin impregnated. The body is dense, porosity is very low. It blocks acid penetration, resists corrosion and aging. It is the first choice for phosphoric acid extraction tanks, acid washing equipment and acid storage tanks.
- Graphitized carbon brick adds high-purity graphite. It has better thermal stability and thermal conductivity. Its thermal expansion coefficient is low. It handles alternating high and low temperature, resists scouring, resists cracking. It suits complex working conditions with large temperature fluctuations.
By Impregnation
- Non-impregnated carbon brick keeps its original pores. Porosity is ≥8%. It gets no impregnation treatment. Corrosion resistance is lower. The process is simple, so cost is lower. It suits dry lining or non-liquid areas.
- Resin-impregnated carbon brick is soaked in impregnant. Quality is more stable, strength is higher. The impregnating agent raises corrosion resistance, especially in molten iron. Porosity is ≤0.5%–1.0%. It is fully leak-proof. The process is complex, so cost is higher.

One-Stop Anti-corrosion Carbon Brick Supply
REBO YJ-5 furan resin mortar is the matching mortar for anti-corrosion carbon bricks. It is a two-component system: furan resin liquid plus carbon or graphite powder. This system resists hydrofluoric acid (HF). Ordinary silicate mortars cannot handle HF. The carbon or graphite filler in YJ-5 is chemically compatible with carbon bricks. Joint and brick behave as one continuous carbon-based lining. YJ-5 does not resist strong oxidizing acids. It is not suitable for nitric acid or concentrated sulfuric acid service. Typical uses: HF-bearing media, acid resistant linings in chemical equipment, and applications specifying carbon bricks as the protective layer.
FAQs About Anti-corrosion Carbon Brick
Q：Why Choose REBO Over Other Brands?
A: REBO’s core strength is not a single index. It is full-chain capability from material to solution. We supply carbon bricks. We also provide working condition analysis, lining system design, brick layout drawings, mortar matching advice, and on-site installation guidance. Many suppliers only sell bricks. They do not help with selection. If the mortar is wrong or the installation is poor, leaks still happen.
REBO connects three key steps: brick selection, mortar matching, and installation. This reduces failure risk from the source. We also support custom-shaped and wedge bricks based on your drawings. They fit circular reactors, towers, pipes, and other complex structures. Many standard-product suppliers cannot do this.
Q: Why Anti Corrosion Carbon Brick Is Irreplaceable for HF and Phosphoric Acid?
A: HF Resistance: Chemically inert to hot concentrated hydrofluoric acid. Superior to conventional acid-proof tiles.
Phosphoric Acid Protection: Ideal for attack tanks, storage vessels, and scrubbers. Resists combined corrosion from H3PO4, HF, H2SiF6, and fluoride salts.
Composite Lining Defense: Combines wear resistance, low permeability, and thermal shock resistance. Raises the thermal limit of rubber linings by 20°C.

Q: Anti Corrosion Carbon Brick vs. Graphite Bricks Selection
A: Anti-Corrosion Carbon Bricks: Made from high-purity petroleum coke/anthracite, baked at high temperatures, and resin-impregnated. Features ultra-low porosity (≤10%) and high impermeability. Best for tanks, pickling lines, and strong acid environments.
Graphite Carbon Bricks: Infused with high-purity graphite. Delivers superior thermal conductivity, high thermal stability, low thermal expansion, and excellent spalling resistance. Best for extreme thermal cycling and severe abrasion.
Selection Rule: Choose Anti-Corrosion Carbon Bricks for anti-permeability and strong acid resistance; choose Graphite Bricks for high thermal shock resistance and heat transfer.

Selection Rule: Choose Anti-Corrosion Carbon Bricks for anti-permeability and strong acid resistance; choose Graphite Bricks for high thermal shock resistance and heat transfer.
Q: Can REBO Provide Third-Party Test Reports Such as SGS or TÜV?
A: Yes. Upon customer request, we issue batch-specific third-party inspection reports (e.g., SGS, TÜV, or CNAS) verifying key physical and chemical metrics like apparent porosity, compressive strength, and ash content. See a SGS checking video on YouTube.
Q: What are Installation Precautions for Anti Corrosion Carbon Brick?
A: Method: Apply the push-squeeze technique: scrape, place, rub, push, squeeze, and clean.
Mortar Application: Ensure 100% full mortar coverage with zero air bubbles. Promptly scrape off excess mortar.
Joint Control: Keep precise joint sizes. Small joints cause voids; large joints risk shrinkage cracks.
Blast Furnace Standards: Maintain joints under 0.5 mm (0.3 mm for tapholes). Use clean dry-masonry with a 0.5 mm surface flatness tolerance.

Q: Can Graphitized Cathode Carbon Bricks be used in Blast Furnaces?
A: Application Fit: Graphitized cathode bricks are engineered specifically for aluminum reduction cells, not blast furnaces.
Blast Furnace Standards: Furnace hearths require micro-porous, ultra-microporous, semi-graphite, or high-thermal-conductivity carbon bricks to resist hot metal erosion and alkali attack.
Key Distinction: Cathode bricks prioritize electrical conductivity and molten salt resistance. The two types serve different technical standards and are not interchangeable.

Key Distinction: Cathode bricks prioritize electrical conductivity and molten salt resistance. The two types serve different technical standards and are not interchangeable.
Q: How is the Impregnation Quality and Porosity of Acid Proof Carbon Bricks Testing?
A: Core Metric: Apparent porosity tested via the Archimedes vacuum displacement method (e.g., GB/T 2997 standard).
Test Steps:
Dry the sample to a constant mass and weigh its dry weight.
Vacuum-impregnate with liquid to fill all open pores.
Weigh the saturated surface-dry weight and the suspended weight in liquid.
Calculate open pore volume relative to total bulk volume.
Quality Benchmark: Premium impregnated carbon bricks maintain apparent porosity below 10%. Micro-porous blast furnace bricks require even lower levels.

Q: What is Production Process for Anti-Corrosion Carbon Bricks?
A: Pre-treatment: Calcine anthracite to remove volatiles. Melt and dehydrate pitch (water content < 0.2%).
Batching: Mix calcined anthracite aggregate (~60%) with fine coke powder and pitch binder (15–20%).
Forming: Press under high pressure.
Firing: Fired in a reducing atmosphere with coke dust packing at 1300-1450°C. Soak for 20 hours (total cycle: 240-420 hours).Impregnation: Vacuum/pressure impregnate with resin or pitch to seal all pores.
