Microstructure, hardness, and fracture toughness evolution of hot-pressed SiC/Si 3 N 4 nano/micro composite after high-temperature treatment. Zeitschrift für Metallkunde: Vol. 97, No. 6, pp. 772-777.
Thin film polycrystalline silicon carbide (poly-SiC) doubly clamped microtensile specimens were fabried using standard micromachining processes, and precracked using microindentation. The poly-SiC had been deposited on Si wafers by atmospheric pressure chemical vapor deposition, a process which leads to residual tensile stresses in the poly-SiC thin films; we measured the residual stress

A silicon carbide with a fracture toughness as high as 9.1 MPa.m1/2 has been developed by hot pressing b-SiC powder with aluminum, boron, and carbon additions (ABC-SiC). Central in this material development has been systematic transmission electron microscopy (TEM) and mechanical characterizations.
Scientists from NUST MISIS have found a way to increase the fracture toughness of silicon carbide, a promising structural material for the production of refractory parts, by 1.5 times. These results were achieved due to the formation of reinforcing nanofibers in the structure. In the future, the technology will expand the scope of silicon carbide appliion as a structural and refractory
Six cylinders (16 cm diameter with 6 mm wall thickness) were manufactured from two unreinforced aluminum alloy and four silicon carbide (SiC) whisker reinforced aluminum composites. Curved, subthickness, Charpy sized specimens were used to measure the fracture toughness, K Ic in accordance with ASTM E 399.

Silicon Carbide Ball Appliions – Silicon carbide is an ideal material for sealing rings and bearings. – Silicon carbide is frequently used in semiconductor and coating industries. – Special bearings and pumps, electric switches and sensors, medical instruments.
Traditionally, pump manufacturers used SiC (silicon carbide) for bushings and bearings in these pumps because of its high hardness and ability to withstand abrasive wear in solid media. Since the early 1980s, OEM pump manufacturers have been using sintered SiC bearings for the stationary and rotating components of tubular casing pumps.
Silicon Nitride Powder has high mechanical strength, fracture toughness, and it is resistant to deformation at room temperature as well as at elevated temperature. Si3N4 differs from other ceramics because it doesn’t melt, but, between 1800 and 1900 °C, it decomposes and sublimates into Si and N.
