Fabrication method of alumina-zirconia complex porous ceramics

摘要

The present invention relates to a method for preparing an Al ₂ O ₃ -ZrO ₂ composite ceramic porous body using a sol-gel method from aluminum alkoxide and zirconium alkoxide, and more specifically, without adding a particle filler or a forming agent, aluminum isopro Al ₂ O ₃ -ZrO ₂ composite powder was prepared by in-situ synthesis from sol-gel process from aluminum isopropoxide and zriconium butoxide, followed by calcination step. And a method for producing an Al ₂ O ₃ -ZrO ₂ composite ceramic porous body having uniform pores having a size of 200 to 2000 nm through a sintering step.;Sol-gel method, alumina-zirconia composite ceramic porous body
