Excellent Thermal Shock Resistance Advanced Ceramic Material

In harsh industrial settings characterized by high temperatures, corrosion, abrasion, and severe thermal shock, conventional materials often fail rapidly, leading to reduced productivity and soaring maintenance costs. Silicon Nitride Bonded Silicon Carbide (Si₃N₄-SiC) products are advanced material solutions engineered to conquer these extreme challenges.
Core Material Advantages
The superior performance of our products begins with the selection and optimization of core raw materials. We use self-produced large-crystal black silicon carbide as the premium base material, creating a composite ceramic material that combines high strength with excellent chemical stability.
  • Exceptional Wear Resistance: Abrasion resistance is 3.13 times that of traditional wear-resistant steel (e.g., Cr15Mo3), while its weight is only one-third, significantly reducing equipment load and extending service life.
  • Superior Corrosion Resistance: Demonstrates extreme stability in aggressive chemical environments (strong acids, alkalis), with far lower mass loss due to corrosion compared to ordinary silicon carbide and alumina ceramics.
  • Excellent Thermal Shock Resistance: Very low coefficient of thermal expansion combined with a suitable elastic modulus ensures the products can withstand severe thermal cycling without cracking.
Performance Parameters
Through stringent production process control, we ensure product performance meets and exceeds industry standards. Categorized into three main types based on form and application needs:
Performance Parameter Refractory Brick Products Kiln Furniture Products Custom-Shaped Products
Apparent Porosity (%) ≤ 16 ≤ 16 ≤ 14
Bulk Density (g/cm³) ≥ 2.65 ≥ 2.65 ≥ 2.68
Cold Crushing Strength (MPa) ≥ 160 ≥ 170 ≥ 180
Cold Modulus of Rupture (MPa) ≥ 45 ≥ 45 ≥ 50
Hot Modulus of Rupture (1400°C, MPa) ≥ 20 ≥ 20 ≥ 20
Refractoriness Under Load (0.2MPa, °C) ≥ 1500 ≥ 1600 ≥ 1700
Maximum Service Temperature (°C) 1550 1600 1550
All product series feature excellent thermal conductivity (≥16 W/m·K) and a very low coefficient of thermal expansion (≤4.18×10⁻⁶/°C at 1000°C), ensuring efficient heat transfer and dimensional stability.
Corrosion Resistance Verification
In the realm of chemical corrosion, our Si₃N₄-SiC material demonstrates dominant performance. The following comparison of mass loss under standard test conditions reveals its unparalleled corrosion resistance:
Test Solution (Concentration) Temperature Si₃N₄-SiC Comparative Material: SiC Comparative Material: Al₂O₃
98% Concentrated Sulfuric Acid 100°C < 0.2 g/m² > 100 g/m² 65.0 g/m²
70% Nitric Acid 100°C < 0.2 g/m² > 100 g/m² 70.0 g/m²
25% Potassium Hydroxide 100°C < 0.2 g/m² > 100 g/m² 60.0 g/m²
53% Hydrofluoric Acid 25°C 0.2 g/m² 8.5 g/m² 55.0 g/m²
10% HF + 57% HNO₃ 25°C < 0.2 g/m² > 100 g/m² 72.0 g/m²
Flexible Customization & Applications
We not only supply standard specification products but also specialize in developing and manufacturing custom-shaped products with complex geometries and stringent performance requirements based on specific customer operating conditions.
Key Application Areas:
  • Non-Ferrous Metal Smelting: Electrolytic aluminum cell linings, furnace components for melting
  • High-Temperature Industrial Kilns: Kiln furniture (shelves, rollers), furnace linings, burners
  • Power & Metallurgy: Circulating Fluidized Bed (CFB) boiler linings, submerged arc furnace parts
  • Wear & Conveyance Systems: Lining plates, nozzles, cyclones for powder processing equipment
  • Chemical & Environmental Protection: Structural parts, sealing components in highly corrosive environments
Choosing our Silicon Nitride Bonded Silicon Carbide products means more than selecting a material; it means opting for higher productivity, lower total cost of ownership, and more reliable production assurance.
