Tempered Glass Glass strengthened by intensive heat treatment during manufacturing. 

Aluminosilicate glasses are used commercially because they can be chemically strengthened and withstand high temperatures. Thus apphcations include airplane windows, frangible containers, lamp envelopes, and flat panel display devices. 

Glass—PVB laminates become mote rigid with a decrease in temperature, and below —7° C approach the performance of soHd glass. At temperatures above 38°C these laminates ate less rigid and provide improved penetration resistance. Some appHcations utili2e he at-strengthened or tempered glass for...

Aesthetic dental ceramics are essentially glass-matrix materials with varying volume fractions of crystalline fillers. Crystalline fillers are used in the glass matrix both for dispersion strengthening, usually at volume fractions of 40—70%, and for altering optical properties, usually at low volume fractions. Dental ceramics are generally manufactured from two distinct classes of materials, ie, beneficiated feldspathic minerals and glass—ceramics.
