烧结碳化硅: A Primer

烧结碳化硅, often abbreviated as SiSiC or SSiC, is a type of ceramic manufactured through a process called sintering. Silicon carbide powder is heated to high temperatures, causing the individual particles to bond together and form a solid, dense material. This process results in a ceramic that’s incredibly hard, resistant to wear and corrosion, and able to withstand high temperatures and pressures.

The Sintering Process: From Powder to Power

The sintering process is what transforms silicon carbide from a simple powder into a powerhouse of a material. It involves heating the silicon carbide powder to temperatures of 2000°C or higher in a protective atmosphere to prevent oxidation. The heat causes the silicon carbide particles to bond together, forming a dense, solid material.
