Silicon Carbide Blocks (SiC Blocks) – High‑Performance Integrated Refractory and Structural‑Functional Materials

Silicon Carbide Blocks are dense ceramic‑metal composite materials produced from high‑purity silicon carbide as the primary raw material through high‑pressure forming and high‑temperature sintering, with a silicon carbide content of ≥90%. They serve as key refractory and structural materials in high‑temperature industrial furnaces, wear‑ and corrosion‑resistant components, and special functional devices. The product offers core advantages such as exceptional thermal conductivity, extreme high‑temperature strength, outstanding thermal shock resistance, and excellent chemical inertness, along with characteristics including high bulk density, low porosity, and stable dimensional accuracy. It can operate for extended periods in oxidizing or reducing atmospheres above 1600°C, significantly improving furnace energy efficiency, extending the service life of thermal equipment, and ensuring the stability and safety of high‑temperature processes.

Produced using sub‑micron silicon carbide powder and advanced sintering aid systems, through reaction‑bonded or recrystallization processes, the product exhibits well‑matched strength and toughness, low thermal expansion coefficient, and resistance to molten metal and slag erosion. It effectively resists high‑temperature deformation, slows the propagation of thermal stress cracks, and inhibits high‑temperature oxidation‑induced silicon loss. It is particularly suitable for high‑end industrial applications with stringent requirements on the integrated thermal‑mechanical‑chemical performance of materials, such as steel industry reheating furnace skid rails, ceramic roller kiln load‑bearing beams, polysilicon casting furnace hot zones, critical linings for waste‑incineration furnaces, and semiconductor heat‑treatment equipment.

We provide high‑temperature industries, new‑energy sectors, and advanced‑manufacturing enterprises with multiple purity grades (90%/97%/99%), various size specifications, and customizable surface treatments for Silicon Carbide Blocks, along with application‑technical solutions. We are committed to being your core material partner in achieving the longevity, efficiency, and cleanliness upgrades of high‑temperature equipment.
