High-temperature kiln furniture refers to a general term for a series of refractory components used in high-temperature industrial kilns (such as ceramic kilns, lithium battery sintering kilns, etc.) to carry, support and protect the products being fired. Although they are not end products themselves, they are indispensable key auxiliary tools in the high-temperature firing process and are known as the "skeleton" and "guardian" of kilns.
High-performance high-temperature kiln furniture must meet stringent requirements such as extremely high refractoriness, excellent high-temperature strength, outstanding thermal shock resistance stability, and good chemical inertness. Common materials include cordierite, mullite, silicon carbide (SiC), and alumina. Among these, reaction-sintered silicon carbide (SiC) has become the first choice in many high-end application fields due to its high strength, high thermal conductivity, and excellent thermal shock resistance.
It bears the crown blank at high temperatures (1300°C-1600°C), ensuring uniform heat transfer and preventing pollution and damage. It is a key guarantee for the temperature control of dental sintering furnaces and the quality of crowns.
Silicon carbide ceramics: Built for extreme environments, they possess properties such as high hardness and high thermal conductivity, and are irreplaceable in the fields of wear resistance, corrosion resistance, high temperature and thermal management.
Zirconia sintering plate: A rare earth refractory pad with corrosion resistance and high temperature resistance, used for sintering dielectric ceramics, electronic components and other products to prevent adhesion and protect electromagnetic properties.
The unique effective pores of porous high-alumina saggers can generate a siphon effect during the low-temperature calcination of powders, helping to completely remove moisture and organic substances, and perfectly adapting to the calcination needs of high-purity ceramic powders.
Suitable for continuous furnaces and vacuum furnaces, it is used for sintering MIM stainless steel parts. With reasonable porosity and high-purity inert composition, it ensures that parts are free from problems such as carburization and decarburization, and has excellent sintering performance.
Magnesium Oxide Ceramic Crucible: Sintered from high-purity MgO at high temperatures, it can withstand 2800°C, resist erosion by alkaline slag, and is suitable for high-end smelting of precious metals and special alloys. It is a key consumable in scientific research and high-end metallurgy.
