Description

소결성 및 기계적 성질이 우수한 알루미나-지르코니아 복합체 제조 방법Method for producing alumina-zirconia composite with excellent sinterability and mechanical properties

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도 pH 변화에 따른 ZrOC12의 적정량변화를 나타내는 그래프.1 is a graph showing a change in the appropriate amount of ZrOC12 according to the pH change.

Claims (1)

95% 이상의 순도와 100μm 이하의 입경을 가진 알루미나를 물을 매질로 하여 pH 6 이하에서 잘 분산 시킨후, 지르코늄염 용액을 알루미나와 중량비로 1 : 1까지 적정하여 계면 유기 코팅공정에 의하여 알루미나 입자 주위에 지르코니아 전구체로 코팅된 복합분체를 통상의 방법으로 건조 및 하소하여 제조함을 특징으로 하는 소결성 및 기계적 성질이 우수한 알루미나-지를코니아 복합체 제조 방법.After alumina having a purity of 95% or more and a particle diameter of 100 μm or less is well dispersed at pH 6 or less using water as a medium, the zirconium salt solution is titrated to 1: 1 with alumina in a weight ratio, and then around the alumina particles by an interfacial organic coating process. A method for producing an alumina-zirconia composite having excellent sinterability and mechanical properties, characterized in that the composite powder coated with the zirconia precursor is dried and calcined by a conventional method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
