What is the difference between tempered glass and heat-resistant glass?

With the development of modern society, glass, as a living material, has been applied to various occasions. There are a wide variety of glass types, and each type of glass has different material performance characteristics, such as tempered glass and heat-resistant glass. So, what are the differences between tempered glass and heat-resistant glass?

1. Different applications:

Tempered glass is used in construction, building templates, decoration industry, furniture manufacturing industry, home appliance manufacturing industry, electronics and instrumentation industry, automobile manufacturing industry, daily necessities industry, and special industries. And heat-resistant glass is used in the daily necessities industry, such as industrial boiler mirrors, mechanical equipment window glass, etc.

2. The impact of temperature changes varies:

Heat resistant glass refers to glass containing strong heat-resistant components such as boric acid and silicic acid, which can withstand rapid temperature changes. It is a special type of glass that can withstand temperature differences between hot and cold fusion, and has a series of excellent properties such as low expansion, thermal shock resistance, high temperature resistance, corrosion resistance, and high strength. So it is safe to use tempered glass in ovens and microwaves, as sudden temperature changes in the microwave may cause it to burst. In the process of making tempered glass, due to the presence of "nickel sulfide" inside, the glass expands with time and temperature, and there is a possibility of self explosion. It cannot be used in the oven at all.

3. Different crushing methods:

When heat-resistant glass breaks, it does not break but instead produces cracks and does not scatter. Heat resistant glass does not pose a risk of self explosion due to nickel sulfide. Heat resistant glass gradually cools down, and there is no condensation energy inside the glass, so it will not scatter when broken. When tempered glass breaks, it will burst and scatter. During the tempering process, pre stress and condensed energy are formed inside the glass. Therefore, when it breaks or self explodes, the condensed energy will be released, forming fragments that scatter and producing explosive sounds.

The above content explains the differences between tempered glass and heat-resistant glass, hoping to be helpful to everyone.
