The main chemical constituents of ordinary glass

The main chemical constituents of ordinary glass

Answer:

Glass is a silicate product that we can see every dayThe window glass is the most common glass, the glass is called ordinary glass. Manufacture of ordinary glass raw material is sodium carbonate, limestone and quartz. The production, the raw materials are crushed and mixed in proper ratio, add heat strengthened glass kiln. Raw material melting happened after the complex physical and chemical changes. Which is the main reaction:Na2CO3SiO2 Na2SiO3CO2 hav'eCaCO3SiO2 CaSiO3CO2 hav'e
In the process of making glass, if you add some metal oxides, can also be made of colored glass. For example, adding Co2O3 (cobalt oxide) after the glass is blue, after joining the Cu2O glass is red. We see the ordinary glass, generally pale green, this is because the raw material is mixed with two valent iron for the sake of.There are many kinds of glass. Besides the ordinary glass introduced above, there are some other kinds of glass, such as quartz glass, optical glass, and so on
The raw materials for making ordinary glass are soda ash, limestone and quartzThe composition of common glass chemical oxides (Na2O, CaO, 6SiO2), the main component is silica
