Characteristics-
PSA:
34.14000
Physical Properties:Colorless amorphous (i.e., fused silica) or crystalline (i.e., quartz) material having a low thermal expansion coefficient and excellent optical transmittance in far UV. Silica is insoluble in strong mineral acids and alkalis except HF, concentrated H3PO4, NH4HF2, concentrated alkali metal hydroxides. Owing to its good corrosion resistance to liquid metals such as Si, Ge, Sn, Pb, Ga, In, Tl, Rb, Bi, and Cd, it is used as crucible container for melting these metals, while silica is readily attacked in an inert atmosphere by molten metals such as Li, Na, K Mg, and Al. Quartz crystals are piezoelectric and pyroelectric. Maximum service temperature 1090°C.

Appearance:White to yellow suspension
Density:2.2-2.6 g/mL at 25 °C
Melting Point:>1600 °C(lit.)
Boiling Point:>100 °C(lit.)
Flash Point:2230°C
Refractive Index:1.46
