Introduction of Silicon Carbide Plates

Silicon Carbide Plates are high-performance ceramic plates made from silicon carbide (SiC) and have excellent resistance to high temperatures, abrasion, and chemical stability. Silicon carbide is an advanced engineering ceramic material known for its high hardness, high thermal conductivity, and thermal shock resistance. Widely used in high-temperature, corrosive, and high-wear industrial applications, silicon carbide plates are efficient, durable, and reliable engineering components.

Features of Silicon Carbide Plates

High hardness and wear resistance: Silicon carbide has a high hardness, second only to diamond and cubic boron nitride, which can effectively resist wear and prolong service life.

Excellent high-temperature resistance: able to work stably in high-temperature environments above 1600°C.

High thermal conductivity: excellent thermal conductivity, suitable for scenes requiring rapid heat dissipation.

Thermal shock resistance: able to withstand rapid temperature changes and suitable for frequent heating and cooling conditions.

Chemical Stability: Extremely resistant to acids, alkalis, and most molten metals.

Low coefficient of thermal expansion: good dimensional stability during temperature changes, reducing the risk of cracking due to thermal stress.

High mechanical strength: high flexural strength and fracture toughness, able to withstand large mechanical stresses.

Electrical insulation: Maintains good electrical insulation properties at high temperatures and is suitable for electronic and electrical applications.

Question 5: Can Silicon Carbide plates withstand rapid temperature changes?

Answer: Silicon carbide plates have excellent thermal shock resistance and are able to maintain structural stability in the face of rapid temperature changes. This is because silicon carbide possesses a low coefficient of thermal expansion and high fracture toughness to effectively resist stresses caused by temperature fluctuations. In addition, the high thermal conductivity of silicon carbide helps to distribute heat quickly and evenly, reducing the risk of localized overheating. Nonetheless, to optimize this property, extreme temperature surges should be avoided as much as possible, especially during cold starts or sharp stops, to prevent potential thermal cracking. Proper design and operational management can help maximize the thermal shock resistance of silicon carbide plates.
