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.
