High Temperature Resistance Glass

What is the high temperature resistance glass?

Thermal stability is a range. For ordinary glass, the thermal is between -20 degrees and -100 degrees, with a temperature difference of no more than 30 degrees for sudden heating or cooling. For tempered glass, the safe temperature range is from -100 degrees to 280 degrees, during which it can be quenched or suddenly heatedGlass is an amorphous inorganic non-metallic material, generally made from various inorganic minerals (such as quartz sand, borax, boric acid barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with a small amount of auxiliary raw materials. Its main components are silicon dioxide and other oxides.

The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 Na2O CaO 6SiO2, etc. The main component is a silicate complex salt, an amorphous solid with an irregular structureIt is widely used in construction, for windproofing and shading, and is a mixture. Additionally, colored glass containing certain metal oxides or salts can show, and some transparent plastics (such as polymethyl methacrylate) are sometimes referred to as organic glass.

Why can’t some glass withstand high temperatures?

glass cannot withstand high temperatures: Ordinary glass is the most widely used, generally in storage bottles, ashtrays, vases, and other glass products. It not need to be heated during use. Because the heat resistance of ordinary glass is quite average, it is not recommended to heat or quench it (for example putting it in the refrigerator when the temperature is high), as the temperature difference for ordinary glass should not exceed 70 degrees. What is the highest temperature that-resistant glass can withstand?

Tempered glass can withstand a maximum temperature of 600 degrees when heated evenly, as exceeding 600 degrees would bring close to the glass’s softening point. Moreover, when heated above 400 degrees, the mechanical properties of tempered glass will gradually decrease.

How many temperature does ordinary glass withstand?

It can withstand 400 degrees. All glass is formed at a high temperature of nearly 1000 degrees Celsius, that any ordinary glass product can easily withstand 400 degrees Celsius. Ordinary glass will have corresponding impurities added according to different needs, with a lower of silicon dioxide, generally able to withstand 600 degrees. However, the heat resistance of tempered glass should not exceed 650 degrees when heated, and its mechanical properties will gradually decrease after exceeding 388 degrees。
