Fine defective structure of silicon carbide powders obtained from different starting materials

The fine defective structure of silicon carbide powders obtained from silicic acid-saccharose, aerosil saccharose, aerosil-sarbon black, and hydrated cellulose-silicic acid gel systems was investigated. The relation between IR absorption characteristics and the microstructure of SiC particles obtain...

Description
Summary:The fine defective structure of silicon carbide powders obtained from silicic acid-saccharose, aerosil saccharose, aerosil-sarbon black, and hydrated cellulose-silicic acid gel systems was investigated. The relation between IR absorption characteristics and the microstructure of SiC particles obtained from different starting materials was established. The numerical relationship between the lattice parameter a and the frequency VTO is presented.
