Silicon carbide (SiC) ceramic is an ideal material for mechanical seal because of its super hardness, high strength, low friction coefficient, good thermal conductivity, and resistance to friction and wear. However, due to relatively high resistivity of SiC ceramic, the triboelectric charge caused by rubbing of mechanical seal end-faces could not be released. It is terrible that the

Direct sintered silicon carbide segment possesses largest share in the market due to its properties that are favorable for industrial appliion and also it has highest grades. Based on appliion, silicon carbide ceramics market is classified into ceramic armor
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.

Recrystallized silicon carbide (RSIC) is a pure silicon carbide material with approximately 11 to 15 % open porosity. This material is sintered at very high temperatures from 2,300 to 2,500° C, at which a mixture of extremely fine and coarse grains is converted to a compact SiC matrix without shrinkage.

Abstract: A reaction sintered silicon carbide-based product, including a silicon carbide component, a bond component, wherein the bond component includes silicon oxynitride in excess of any silicon nitride of the bond component, and at least one boron
Silicon carbide is a man-made material manufactured through heating silica sand and carbon to high temperatures in the furnace technique. Silicon carbide is an extremely hard material (Mohs hardness 9), is chemically inert and does not melt.Silicon Carbide has a high thermal conductivity, a low coefficient of thermal expansion, is thermal shock and abrasion resistant and has strength at high

The electrochemical behavior of solid‐sintered silicon carbide was investigated under high current densities in alkaline solutions. The use of potentiodynamic as well as chronoamperometric measurements show that the anodic dissolution takes place as a transpassive mechanism under formation of a metastable passive layer.

Upgrade your shell or tube heat exchanger system to the industry’s most high-performance, efficient tubing option — Saint-Gobain’s Hexoloy® SE sintered silicon carbide (SiC) heat exchanger tubes.
C and SiC materials were sintered by the larger 250 ton industrial FAST system, a HP system, and PL sintering system with a targeted dense material geometry of 4×4×0.315 inches3 (101.6×101.6×8 mm3). The resulting samples were studied to determine if the
To improve the efficiency of power modules in environmentally friendly vehicles, silicon-carbide (SiC) chips and silicon-nitride (Si3N4) active metal-brazed (A) substrates were bonded by low-pressure silver (Ag) sintering at 220°C and 1 MPa using Ag paste. The initial bond strength of the sintered joint was 35.7 MPa, and the void content and bonding-layer thickness of
Silicon carbide can be sintered up to high densities by means of liquid phase sintering under low gas pressure with AlN-Y 2 O 3, AlN-Yb 2 O 3, and AlN-La 2 O 3 sintering additives. As-sintered materials exhibited fine-grained homogeneous microstructure.
Uncoated self-sintered silicon carbide rings were evaluated using the same test method. The results showed consistent cracking and intrinsic failures at indenter loads of approximately 460 ksi (approximately 3,200 MPa).
Silicon Carbide (SiC) also known as carborundum is a compound of Silicon & Carbon. It occurs in nature as the extremely rare mineral moissanite. Grains of silicon carbide can be sintered together to form very hard ceramics that are widely used in appliions requiring high endurance such as car brakes, car clutches & ceramic plates in bullet proof vests.
