Investigation of growth processes of ingots of silicon

Mar 01, 1978· Silicon carbide ingots as well as plates cut out of ingots were studied by X-ray structural analysis. X-ray topograms from thin platelets were taken by the Lang method [101. The ingots were studied by a modified Schultz method [11]. To obtain the reflec- tion from the ingot top the reflection (00.12) was at boron vapour pressure in the vapour

Microstructure Development in Hot-Pressed Silicon …

Silicon carbide is a desirable material for high temperature structural appliions because of its light weight and outstanding high temperature mechanical properties (high hardness, high creep resistance, good chemical stability). However, the low fracture toughness of commercial SiC (3~5 MPa.m1/2) has detracted from its widespread appliions.
