Answers
Answer ⤵️
Silica, commonly known in the form of quartz, is the dioxide form of silicon, SiO2. It is usually used to manufacture glass, ceramics and abrasives. Quartz is the second most common mineral in Earth's crust. Its chemical name is SiO2.
Explanation:
Vitreous sillica
Vitreous silica is the most refractory glass in commercial usage.
because of the high cost of manufacture, the uses of vitreous silica are mostly limited to astronomical mirrors, optical fibers, crucibles for melting high-purity silicon, and high-efficacy lamp envelopes. In one technique, the glass is obtained by melting high-purity quartz crystals or beneficiated sand at temperatures in excess of 2000°C. In a second technique, SiCl4 is sprayed into an oxy-hydrogen flame or water vapor-free oxygen plasma, reacting to form SiO2 vapors, which deposit on a substrate and are subsequently consolidated at ~ 1800°C.
