摘要
PURPOSE: To simply and stably form a spinel film by keeping a closed space, in which a member to be coated and a spinel material are arranged, at a prescribed spinel vapor pressure by heating in a reducing atmosphere or in an evacuating atmosphere. ;CONSTITUTION: The member to be coated and the spinel material such as MgAl3 O4 powder are adjacently arranged in the closed space. The member to be coated has a smaller evaporative factor than that of the spinel material and an optional shape. The spinel vapor is generated and kept by heating the space in a reducing atmosphere of gaseous hydrogen or in evacuating atmosphere at 1500-1900°C. As a result, the spinel film is vapor deposited on the member to be coated. By using this method, the transmissive alumina-spinel composite is formed by forming a spinel coating film on the transmissive dense alumina and the spinel body is formed by forming the spinel coating film on a combustible material before burning the combustible material.;COPYRIGHT: (C)1994,JPO&Japio
