Extensive Applications of Sapphire Glass

When discussing sapphire glass, people might immediately think of jewelry and adornments. However, it is actually an artificially compressed synthesis of crystalline mirror that differentiates from the natural one. The primary component is alumina, which shares identical physical properties and chemical composition with natural sapphire. Nevertheless, this synthetic version can be conveniently and easily prepared in the laboratory at a highly cost-effective rate.

Sapphire glass has a high density and excellent resistance to wear and damage, which is comparable to the wear resistance of high-tech manufactured ceramics and tungsten-titanium alloys. However, high-tech manufactured ceramics and tungsten-titanium alloys are not so resistant to strong impacts that many materials with similar or higher hardness, such as sandpaper, grinding stones, granite, concrete walls and floors, may scratch the surfaces of them. With excellent dielectric and electrical properties, sapphire glass can be used to manufacture many physical devices. It also has excellent thermal properties, high hardness, high infrared transmission, good resistance to chemical corrosion and good chemical stability. Consequently, it is widely used in infrared and far-infrared military equipment, and can replace other optical materials to manufacture optical components, infrared optical windows and wristwatches.
