    Hydrothermal Reaction Of Silica Sand Contains Some

    Silica sand is commonly used in the foundry industry. With a high melting point of 160 C, the silica sand is normally sintered in a high temperature furnace. However, silica with contents of calcium, aluminium, magnesium, and chlorine, etc. can form low melting point eutectics. Therefore, a relatively low power laser can be used to sinter the silica sand directly.May 24, 2009 Sand is composed of silica (also known as silicon dioxide), and is the starting point for making a processor. Sand used in the building industry is often yellow, orange or red due to impurities, but the type chosen in the manufacture of silicon is a purer form known as silica sand, which is usually recovered by quarrying.
