The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
Because silicon dioxide is a native oxide of silicon it is more widely used compared to other semiconductors like gallium arsenide or indium phosphide. Silicon dioxide could be grown on a silicon semiconductor surface. [46] Silicon oxide layers could protect silicon surfaces during diffusion processes, and could be used for diffusion masking ...

4 (Trisilicon tetranitride) is the most thermodynamically stable and commercially important of the silicon nitrides, [6] and the term ″Silicon nitride″ commonly refers to this specific composition. It is a white, high-melting-point solid that is relatively chemically inert, being attacked by dilute HF and hot H 3 PO 4.

For the p SiO above molten silicon in a quartz (SiO 2) crucible at the melting point of silicon, one study yielded a value of 0.002 atm. [10] For the direct vaporization of pure, amorphous SiO solid, 0.001 atm has been reported. [11] For a coating system, at the phase boundary between SiO 2 and a silicide, 0.01 atm was reported. [12]
Aluminium silicate is a type of fibrous material made of aluminium oxide and silicon dioxide, (such materials are also called aluminosilicate fibres). These are glassy solid solutions rather than chemical compounds. The compositions are often described in terms of % weight of alumina, Al 2 O 3 and silica, SiO 2. Temperature resistance increases ...
