Introduction and Characteristics of Sapphire Glass

Introduction to Sapphire Glass

Sapphire Glass generally refers to synthetic sapphire, which is quite different from natural sapphire as commonly understood by people. It is usually used to manufacture watch mirrors.

Sapphire is the general name for all corundum gemstones except red ruby. Its main component is alumina (Al2O3). Sapphire Glass is a kind of synthetic sapphire, which can be produced easily and inexpensively in the laboratory to produce gem-grade sapphire, whose chemical composition and physical characteristics are identical to those of natural sapphire. Sapphire glass has a composition similar to that of corundum and has a hardness of 9. It can add various chemical elements to produce different colors. Currently, it is commonly used colorless. Sapphire glass has higher advantages than ordinary glass and its price is relatively high. It is mainly used to make high-end watch displays.

The Characteristics of Sapphire Glass

Sapphire glass and ruby glass have superior thermal properties, excellent electrical and dielectric properties, and chemical corrosion resistance. It is resistant to high temperatures, has good thermal conductivity, high hardness, infrared transparency, and good chemical stability. Therefore, it is often used to replace other optical materials to make optical components, transparent infrared optical windows, etc. and is widely used in infrared and far-infrared military equipment, such as night vision infrared and far-infrared aiming devices, night vision cameras, and other instruments. It is also used in instruments for satellites and space technology, windows for high-power lasers, various optical prisms, optical windows, UV and IR windows and lenses, observation ports for low-temperature experiments, and high-precision instruments for marine aviation.

The Advantages of Sapphire Glass

Sapphire is very sturdy and scratch-resistant, and is a more expensive crystal than other crystals. The advantages of sapphire crystals include scratch resistance, fracture resistance, less likelihood of cracking, and less likelihood of breaking. This makes them the preferred choice for exquisite timepieces. Although sapphire is more expensive than the other two crystal options, it has an advantage in that it is scratch-resistant and fracture-resistant. Sapphire glass may be more scratch-resistant, but gorilla glass can bend more in the four-point bending test. Sapphire glass is artificially synthesized, and in fact is not considered glass but a crystal. Sapphire crystal is made at very high temperatures and is made up of crystalline alumina. The harder the glass, the less likely it is to be scratched, and the less impact it will experience.
