Alpha Sintered Silicon carbide does however sace the Pressure Velocity ratios due to the lack of un-reacted free carbon. Either grade of SIC can usually be re-lapped and polished to be reused. If you have any questions please contact us at: E-mail about your mechanical seals appliions
Sintered silicon carbide was patented by the Pittsburgh-based Carborundum Corporation in 1979 under U.S. patent 4,179,299. It is currently held by Saint-Gobain. It was registered and trademarked as Hexoloy in 1984. The first large commercial use for Hexoloy
However, boron carbide is very brittle and undergoes softening past the critical HEL point, unlike similar ceramics such as silicon carbide . This loss of strength limits the material’s performance in critical appliions. The sudden failure of boron carbide under

This report studies the Silicon Carbide Ceramics market, Silicon Carbide has properties remarkably similar to those of diamond – it is one of the lightest, hardest, and strongest technical ceramic materials and has exceptional thermal conductivity, resist
GAB Neumann’s CORRESIC ® product portfolio includes silicon carbide plates, block and tube, and shell and tube heat exchangers.Our individual plates, blocks, and tubes are all made of pressureless sintered silicon carbide. This manufacturing process confers its
Silicon carbide (SiC) has been in use since the late 1800s, beginning as an abrasive material and later finding appliions in a wide variety of industries. In the BaSiCs of SiC blog series, we’ll explore many different features of silicon carbide. Let’s kick things off with
The depth of penetration method was used to ballistically evaluate the performance of silicon carbide as a function of grain size. The hot-pressed silicon carbide was backed by 4340 steel Rc = 35 and impacted by tungsten heavy metal projectiles of L/D = 4 at velocities of 1.6 and 1.75 km/s. The hot-pressed silicon carbide was also compared with reaction-sintered silicon carbide of identical

Silicon carbide, exceedingly hard, synthetically produced crystalline compound of silicon and carbon. Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More
3 Natural Rainbow Silicon Carbide Crystal Specimens.Crystals measures approx. 2.50" across and the total weight is approx. 174 grams. This extremely hard substance (Carborundum) has many appliions, most commonly used as a abrasive second only to
A seal code is an abbreviated method of communiing basic specifiions for the mechanical seal. Sadly, the seal code has been changed with every edition of API 682. Fortunately, the new code, described in API 682 4 th Edition Annex D, is the best to date and includes some concepts and codes from the historical API 610 seal code.
can be observed that the silicon carbide was sintered to about 0.93 of its relative density by using alumina and yttria as sintering additives. This finding was as a result of a eutectic liquid formed between alumina and yttria at sintering temperature of 1930 C.
Worth knowing: Properties of Silicon Carbide (SSiC / SiSiC) Low density (3.07 to 3.15 g/cm 3) High hardness (HV10 ≥ 22 GPa) High Young’s modulus (380 to 430 MPa) High thermal conductivity (120 to 200 W/mK) Low coefficient of linear expansion (3.6 to 4.1x10-6 /K at 20 to 400 C)
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.
