内容記述 | Chemical stability toward water has been investigated for nine kinds of AIN powders which were prepared by two different processes. The powders prepared by reducing and nitriding alumina (A powders) exhibited more excellent chemical stabilities than those prepared by directly nitriding aluminum (B powders). The reason for these phenomena could be attributed to higher surface-activities of the B powders, because they included a large number of fine particles as well as fracture faces which were formed during the grinding process. The chemical stability was improved by surface-oxidation in nitrogen gas containing a trace amount of oxygen (below 5 ppm) at elevated temperatures, irrespective of the preparation method of AIN, though it was more effective for the A powders. The treatment of A powders at higher temperatures resulted in formation of a less amount of Al(OH)3 after dispersion in distilled water, that is in enhancement of chemical stability toward water. However, the treatment at higher temperatures also increased the oxygen content or α-Al2O3 on the surface. In view of high stability and low oxygen content, the treatment was most suitable at 1000℃ for 6 hr. | |||||
