Abstract

The invention discloses a method for preparing an ultra-high-temperature light-weight zirconia setter plate, which comprises the following steps: (1) material selection: respectively select high-purity zirconia fiber, zirconia fine powder and high-purity zirconia sol; 2) Mixing ingredients: Weigh 30-60% of zirconia fibers with a diameter of 2-15 microns and 40-70% of zirconia fine powder with a particle size of ≤0.088mm by mass percentage; add zirconium sol binder and stir and mix; ( 3) The above-mentioned mixed and prepared raw materials are sieved through a sieve and packed into a plastic bag for bundling and storing, and then taken out and sieved twice before being pressed and formed; (4) The above-mentioned pressed and formed solid zirconia is cured and dried; (5) Sintering the solid zirconia after curing and drying at high temperature to obtain the desired high temperature resistant zirconia setter. The method of the invention is novel and effective, and the prepared zirconia light-weight setter plate has high porosity, low heat storage, good chemical stability, light weight and high temperature resistance.

Description

technical field [0001] The invention relates to a preparation method of an ultra-high-temperature light-weight zirconia setter. Background technique [0002] The current setter can withstand a maximum temperature of no more than 1600°C, and its scope of application is relatively limited. The chemical stability of the setter plate is poor during sintering, and the heat storage is too high. Especially when sintering chip electronic components and hard alloy parts, problems such as chemical reaction, cracking, and deformation are prone to occur. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a method for preparing an ultra-high temperature lightweight zirconia setter plate. The setter plate made by this method has high porosity, light weight, low heat storage, and It is conducive to the perfect sintering of chip parts, and has excellent chemical stability; it has a wide range of applicable ...
