A ceramic setter and its preparation method

Abstract

The invention relates to a ceramic load bearing board which comprises the following raw materials in parts by weight: 90-98 parts of yttrium oxide-stabilized zirconium oxide, 1-5 parts of zinc oxide,0.8-3 parts of bismuth oxide, 0.1-0.6 part of antimony oxide, 0.05-0.1 part of nickel oxide and 0.03-0.06 part of manganese oxide. A preparation method for the ceramic bearing board comprises the following steps: mixing materials, adding a binder, baking, pelletizing, carrying out mold-pressing, drying and burning. The ceramic bearing board has the advantages of high strength, high temperature resistance, corrosion resistance, long service life, convenience in use, simple preparation, and the like, and is especially suitable for bearing and baking a zinc oxide piezoresistor.

Description

technical field

[0001] The invention relates to the technical field of ceramic materials, in particular to a ceramic setter and a preparation method thereof. Background technique

[0002] Setter is a kind of functional ceramic, which is the carrier of electronic components in the sintering process. Its quality and performance directly affect the quality, output, energy consumption and cost of fired products. The main performance requirements that a qualified setter plate needs to meet are: no deformation, no cracking, stable chemical properties and good thermal shock resistance when electronic components are sintered at high temperature.

[0003] At present, there are two main types of setter plates used in the firing of zinc oxide varistor products in the industry: one is setter plates made of zinc oxide varistor waste, which has low strength and cold resistance. Poor thermal cycle ability, easy to deform, crack, and short service life; the other is ordinary zirconia sette...
