We have demonstrated a method of producing nanoplatelets or complex well-ordered nanostructures from silicon carbide (SiC) whiskers. Preferential etching of SiC whiskers in a mixture of hydrofluoric and nitric acids (3:1 ratio) at 100 °C results in the selective removal of cubic SiC and the formation of complex structures reseling a pagoda architecture. Possible mechanisms governing
Silicon carbide grit blast media is brittle, sharp, and suitable for grinding metals and low-tensile strength, non-metallic materials. Plastic media blast equipment uses plastic abrasives that are sensitive to substrates such as aluminum, but still suitable for de-coating and surface finishing.
Boron carbide-silicon carbide ceramic composites are very promising armor materials because they are intrinsically very hard. However, their fracture toughness is not very high. Their ballistic performance could be significantly increased if the brittleness of these materials could be decreased. Here we report development of boron carbide-silicon carbide layered ceramics with controlled
The thermal conductivity indies the speed of wholesale brown fused alumina heat transfer when the object is suddenly cold or hot. The thermal conductivity a of silicon carbide can be 6.28 ~ 9.63w.m1.k. that of corundum can be 1.5702.41w.m1.k. The hardness of brown corundum is a little lower than that of common abrasives.
Creep mechanism and microstructure evolution in silicon nitride ceramics Creep mechanism and microstructure evolution in silicon nitride ceramics Lofaj, F. 2007-01-01 00:00:00 Tensile creep processes in a commercial grade of silicon nitride, SN 88, are reviewed with the focus on cavitation and microstructure changes. . Experimental measurements showed that cavitation at multigrain junctions is

That is, threshold character of silicon carbide nanopowder sintering is associated with specificity of its hexagonal cell structure. It is possible to avoid these difficulties by applying a set of measures aimed at suppression of rapid growth, such as a significant decrease in the rate of temperature rise in the vicinity 2080°C or doping of grain boundaries by a small amount of corresponding
