Good thermal shock resistance cordierite mullite setter disc for powder metallurgy
Understanding Cordierite and Mullite
Before delving into the specifics of the cordierite mullite setter disc, it is essential to understand the materials that constitute it. Cordierite is a magnesium aluminum silicate mineral known for its excellent thermal stability, low thermal expansion, and resistance to thermal shock. These properties make cordierite an ideal choice for applications that involve high temperatures and rapid temperature changes.
Mullite, on the other hand, is a silicate mineral that is primarily composed of aluminum silicate. It is renowned for its high strength, thermal stability, and resistance to chemical corrosion. The combination of cordierite and mullite results in a setter disc that exhibits superior mechanical properties and thermal performance, making it particularly suitable for the demanding conditions of powder metallurgy.
The Role of Setter Discs in Powder Metallurgy
In powder metallurgy, setter discs are used to support and separate green bodies during the sintering process. The sintering process involves heating the powdered material to a temperature below its melting point, allowing the particles to bond together and form a solid structure. The setter disc provides a stable and non-reactive surface that minimizes contamination and ensures uniform heating.
The cordierite mullite setter disc is specifically designed to withstand the high temperatures and mechanical stresses encountered during sintering. Its low thermal expansion coefficient helps to prevent warping and cracking, ensuring that the disc maintains its shape and integrity throughout the process. Additionally, the disc’s excellent thermal conductivity promotes even heat distribution, which is critical for achieving consistent sintering results.
