Sapphire glass. Similar to the steel jade composition, hardness of 9, you can add a variety of chemical elements, generate a variety of colors, and now commonly used is colorless. Its advantages are higher than ordinary glass hardness, the price is relatively high, mainly for the production of high-end watch the mirror. Sapphire glass / ruby glass has a very good thermal properties, excellent electrical characteristics and dielectric properties, and anti-chemical corrosion, it is high temperature, good thermal conductivity, high hardness, through the infrared, good chemical stability. So it is often used to replace other optical materials, optical components, through the infrared optical window, and is widely used in infrared and far infrared military equipment, such as: used in night vision infrared and far infrared sight, night vision cameras and other equipment And optical instruments, as well as windows for high power lasers, various optical prisms, optical windows, UV and IR windows and lenses, low-temperature experimental observation port, high-precision instrumentation in aerospace, etc. To be fully applied.
Sapphire glass (SAPPHIRE CRYSTAL) generally refers to the synthetic sapphire, and people usually understand the jewelry - natural sapphire has a big difference, generally used for the manufacture of watch mirror. It is anti-wear material with tungsten titanium alloy and high-tech ceramics. These materials are resistant to abrasion, but can not withstand strong impact, while some of the same hardness or higher material (such as: grinding stone, sandpaper, nail down, granite surface, concrete walls and the ground, etc.) are likely Scrape the surface of these materials. Sapphire is a corundum gem in addition to the red ruby, the other colors known as corundum gem, the main component is alumina (Al2O3). Sapphire glass refers to the synthetic sapphire, in the laboratory can be easily and cheap to produce gem-level sapphire, its chemical composition and physical properties and natural sapphire the same.
On the surface Oh breath, the fog quickly spread out for the sapphire crystal glass, the general situation is when you put the mouth from the top of the mirror to open the moment to disperse, look at the surface when you can not see the fog.
Two tapping method
With nails (if cut too short, find the seller to borrow, ^ _ ^) gently tapping the surface, remember, must be light, false is likely to break, when you want Compensation is not good, if the sound is dull sapphire crystal surface, if it is a general crystal or glass, the sound is relatively crisp.
Three. Dripping method
Conditional circumstances, a drop of water on the surface, and then the surface up, the water will not spread, and slowly slipped, must be slow, very slow very slow, this is the sapphire crystal.
