Hexoloy - Wikipedia

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

SiC’s Unique Properties and Appliions | Wolfspeed

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

A study of the effect of grain size on the ballistic …

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

API Seal Codes | Seal FAQs

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.

THE MICROSTRUCTURE, PHYSICAL AND MECHANICAL PROPERTIES OF SILICON CARBIDE …

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.

Non-oxide Ceramics – Silicon Carbide (SiSiC/SSiC)
