In the 1930’s, the silicon carbide replaced the spark gaps. In the mid 1970’s, zinc oxide gapless arresters, which possessed superior protection characteristics, replaced the silicon carbide arrester. A great nuer of silicone carbide arresters are still in service
Effect of chemical elements on steel - Tubecon
As described below the effect of silicon on steel is the same as manganese in some instances, but to a smaller degree. This and other effects which silicon has on steel is described in this section. Silicon is the same as Manganese in the sense that all steel grades contains silicon and even though it is less than manganese, it still increases the strength and hardness.

Stainless Steel - General Information - Alloying Elements …
SiIicon (Si): Silicon is used as a deoxidising (killing) agent in the melting of steel and as a result most steels contain a small percentage of Silicon. Cobalt (Co): Cobalt becomes highly radioactive when exposed to the intense radiation of nuclear reactors, and, as a result, any stainless steel that is in nuclear service will have a Cobalt restriction, usually approximately 0.2% maximum.
Boron carbide - Wikipedia
Boron carbide (chemical formula approximately B 4 C) is an extremely hard boron–carbon ceramic and covalent material used in tank armor, bulletproof vests, engine sabotage powders,  as well as numerous industrial appliions. With a Vickers hardness of >30 GPa, it is one of the hardest known materials, behind cubic boron nitride and diamond.
Tungsten Carbide Properties
9. Specific Heat - Tungsten carbide ranges from about 50% to 70% as high as carbon steel. 10. Weight - The specific gravity of tungsten carbide is from 1-1/2 to 2 times that of carbon steel. 11. Hot Hardness - With temperature increase to 1400 F, tungsten

18/8/2018· Clay graphite crucibles are OK, but they are very susceptible to thermal shock, which means if they are heated too quickly they will crack, silicon carbide crucibles do not suffer from thermal shock. A five to seven year service life from a high quality silicon carbide crucible is not unusual at hobby foundry level, as long as the crucible is properly cared for.
