Titanium | Revolvy

Titanium Titanium is a chemical element with syol Ti and atomic nuer 22. It is a lustrous transition metal with a silver color, low density, and high strength. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791, and was named by Martin Heinrich Klaproth after the Titans of Greek mythology.

Pressed crucibles | Plansee

With our many years of experience in the field of powder metallurgy, we produce crucibles of a particularly high density and purity. By correctly filling the mold used for the crucible and carefully controlling the temperature distribution during sintering, we achieve uniform wall and base thicknesses - an important prerequisite in achieving the high level of creep resistance that

Silicon Carbide (SiC) | Morgan Technical Ceramics

Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are

2019-4-24 · This time I worked in the open hearths. The open hearth is where they made steel at that time. Pig iron comes out of the blast furnaces at something like 4 percent carbon with a lot of silicon in it, and maybe phosphorous and manganese, and you have to get those impurities out of the steel.

2009-7-27 · The ceramic itself is typically aluminum oxide, silicon carbide, or boron carbide, Hoppel says. Other ceramics that have been used in armor include titanium diboride, aluminum nitride, silicon nitride, and tungsten carbide. These ceramics are far harder than those used to make consumer goods and in some cases are nearly as hard as diamond.
