Preparation method of high-precision ceramic ferrule
The invention provides a preparation method of a high-precision ceramic ferrule and a preparation method of partially stabilized zirconium oxide powder for the high-precision ceramic ferrule. The preparation methods provided by the invention have the following advantages: firstly, silicon oxide, molybdenum oxide, zinc oxide, scandium oxide and holmium oxide are adopted, so that the thermal stress property of partially stabilized zirconium ceramic is high, the thermo-mechanical property of zirconium oxide is improved, and the ferrule material can be higher in strength, high in thermal shock resistance, low in deformation possibility and free from cracking; secondly, through an ethylene-vinyl acetate copolymer, TPEE, PTT, HDPE, polyformaldehyde and the like are polymerized in an interpenetrated manner to form an interpenetrated network structure, so that the obtained ceramic ferrule is low in deformation possibility and relatively high in precision; thirdly, an adopted organic binding agent has high liquidity, so that the ceramic ferrule is high in homogeneity and free from cracking; finally, due to the sequence of adding the organic binding agent during mixed refining, the feeding rheological property can be relatively high, a blank material can be easier to degrease, and then the prepared ceramic ferrule can be prevented from cracking.
