Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand.Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product.
Most sand and ceramic technologists have calculated that when Wlistite (FeO) attacks silica sand, it forms a solution of approximately 20% silica with the ferrous oxide (FeO) which is fayalite (Fe2 SiO4). The melting point of fayalite is less than 2190° F. ( 1199° C.).
Silica sand is mainly used because of its thermal conductivity. It can absorb and transmit heat while allowing the gases generated during the thermal degradation of binders to pass through the grains. As a molding material, the sand is compacted and shaped according to the mold pattern that is going to be produced, as well as to create cavities.
