Silicon Carbide (SiC) | Morgan Technical Ceramics

Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles.

Silicon Carbide Analysis and Usage

2013-4-10 · Silicon Carbide Analysis. The Lely method is used for growing large single crystals of SiC. These large crystals are then cut down into gems called as ‘synthetic moissanite.’ SiO 2 found in plant material can be used to produce SiC with high surface area. Assessing the quality of SiC is a key step in the processing of SiC.

Raman spectroscopy studies of carbide derived …

The Raman spectra of a nuer of carbide derived carbons (CDCs) synthesised from TiC at 700, 800, 900, 1000, 1100 and 1200 °C and from VC, WC, TaC, NbC, HfC and ZrC made at 1000 °C have been recorded using laser excitation wavelengths of 514 and 785 nm.The spectra show two main features, the D- and G-peaks situated around 1350 cm −1 and 1600 cm −1, respectively.

ISO 21068-1:2008(en), Chemical analysis of silicon …

ISO 21068, Parts 1 to 3, are applicable to the analysis of all refractory products as classified in ISO 10081 [10] to [13] (shaped) and ISO 1927 [3] (unshaped) and raw materials containing carbon and/or silicon carbide. Therefore, ISO 21068, Parts 1 to 3, covers the full range of analysis from pure silicon carbide to oxidic refractory composition with low-content silicon carbide and/or nitrides.
