Abstract

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.

Description

technical field [0001] The invention relates to the technical field of ceramic electronic components, in particular to a method for preparing a high-precision ceramic ferrule. Background technique [0002] In the field of optical fiber communication technology, optical fiber connectors can be used to transmit optical signals, and their core and basic components are ferrules, which play the role of media for connection, conversion, and data transmission. They are the most basic and important components of a series of optical communication products. Passive components. [0003] The most widely used ceramic material at present is zirconia ceramic ferrule, which is prepared by injection molding of zirconia powder. The injection molding process technology originated from the field of plastic molding and was later extended to the molding of ceramics. The basic process includes pretreatment of powder, heating and mixing of powder and binder to form feed, and after the feed is cool...
