Abstract

The invention discloses an anti-adhesive and high-temperature-resistant setter and a preparation method thereof. The slurry is evenly sprayed on the surface of a substrate and sintered to form a coating; wherein, the slurry is composed of yttrium oxide, zirconium oxide, oxide It is obtained by uniformly mixing tungsten and binder; the matrix is ​​obtained by processing zirconia into a honeycomb structure. In the invention, the coating is processed on the surface of the honeycomb matrix, so that the setter has better performances of anti-bonding and high temperature resistance. The setter can be used for sintering easily sintered powders and materials with high chemical activity and easy reaction with crucible materials, and has good promotion and application value in the fields of battery materials, ceramic capacitor firing, high-temperature sintering and other fields.

Description

technical field [0001] The invention relates to a setter, in particular to an anti-bonding and high temperature resistant setter and a preparation method thereof. It belongs to the technical field of sintering devices. Background technique [0002] The appliances used in industry to burn various substances (such as powders, ceramics, metals, etc.) are collectively referred to as burners. The burner plate, the burner bowl, and the burner bowl are all common burners. In addition to heat resistance and mechanical strength, the setter is required to have properties that do not react with the substance to be fired at high temperatures. Most of the setters used today are cordierite, mullite and corundum, which are heavy refractory materials with large heat absorption, problems such as energy efficiency, poor furnace efficiency and high production cost. Moreover, it is easy to react with the burning material at high temperature, so that the material sticks to the wall during bur...
