Gas pressure sintered silicon nitride (GPSSN) is a sintering processing at high temperature after isostatic pressing of silicon nitride powder with other additives. The nitrogen pressure (<20mpa) during sintering could restrain the dissociation of si3n4 and get the full sintering at high temperature, which make the silicon nitride products to highest density and lowest porosity.

We report on the deposition of SiC-layers in a newly constructed high-temperature chemical vapor deposition system. With this system SiC-layers are deposited onto tape-casted SiC-ceramic substrates (10/spl times/10 cm/sup 2/) at deposition temperatures ranging from 1200 to 1450/spl deg/C to study the chemical stability, the smoothness, and the electrical resistivity of the SiC-layers. The SiC

Silicon Carbide Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive.
24/7/2018· NEW YORK, July 24, 2018 /PRNewswire/ -- This report analyzes the worldwide markets for Boron Nitride and Boron Carbide in Metric Tons by the following Product Segments: Boron Nitride, and Boron
The Boron carbide, with its cas registry nuer 12069-32-8, has the systematic name of 2,3,4,5-tetraboratetracyclo[184.108.40.206~1,3~.0~2,5~]pentane. This is a kind of black odourless powder, and is stable chemically while is incompatible with oxidizing agents.
2 belief at that time that interactions with the SiO2 substrate were negligible. Later research found that substrate induced disorder is significant. In contrast, epitaxial graphene on silicon carbide is widely used to demonstrate the intrinsic band structure of graphene[9-11] (see Figure 2) that is not
