Description:
01. Silicon dioxide is a compound containing only oxygen and silicon, with the chemical formula SiO2 and commonly known as silica. It is the most common and stable compound of silicon. It is widely distributed in nature and constitutes various minerals and rocks.
02.Silica exists in two states: crystalline and amorphous. The most important crystalline silica is quartz. Pure quartz is colorless, while common sand is silica mixed with impurities. In nature, there is also amorphous silicon called diatomite, which is often used as the adsorbent for glycerol explosives (nitroglycerin).
03.The hardness of crystalline silica is all very high. For example, the Mohs hardness of quartz is 7. Amorphous silicon has a relatively low hardness, among which the harder opal has a hardness of 5.5 to 6.5.
