Borophosphosilie glass (BPSG) is a coating made from a mixture of oxygen and hydrides of silicon (silane – SiH 4), boron (diborane – B 2 H 6), and phosphorus (phosphine – PH 3). It is also called a doped oxide film because it is similar to silicon dioxide with the addition boron and phosphorus, which change its thermal properties.
Silicon Carbide SiC Material Properties - Accuratus
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
Carborundum / Silicon Carbide - The Rock Crystal Shop
Carborundum / Silicon Carbide Carborundum is a man made crystal coining silicon and carbon atoms fused together which sparkles in rainbow colours of gold, pink, green, blue and purple. Carborundum was originally sold as natural "rainbow hematite" and a few other rare crystals that look similar, but is increasingly being correctly known as a man-made silicon carbide.

Calcium carbide is also an intermediate product in the smelting of calcium–silicon alloy. Technical grade calcium carbide is crystallized from the melt and contains ~80% CaC 2 and 10% to 15% CaO (Fig. 19.4).
Silicon Controlled Rectifier Tutorial with Characteristics
Thyristor can be manufactured using a variety of materials such as silicon, silicon carbide, gallium arsenide, gallium nitride, and so on. But, the good thermal conductivity, high current capability, high voltage capability, economical processing of silicon has made it to prefer compared to other materials for making thyristors, hence, they are also called as silicon controlled rectifiers.

Silicon Carbide Powder High Purity Less Price Fast Delivery
Silicon Carbide Powder: The ability of Silicon Carbide to withstand very high temperatures without breaking or distorting is used in the manufacture of ceramic brake discs for sports cars. It is also used in bulletproof vests as an armor material and as a seal ring material for pump shaft sealing where it frequently runs at high speed in contact with a similar silicon carbide seal.
The mobility of the electrons is also greater than in silicon or germanium, and that of the holes similar to those of silicon. To impurify the type p, materials such as zinc, cadmium or copper are used since they introduce permitted levels in the range of 0.08 to 0.37 eV above the valence band of GaAs.
