raw material of silica sand

  • Silica

    Silica is also available as a silicate glass (in frits ). Pure silica minerals (like quartz) have high melting points. In ceramic bodies and glazes other oxides are added to complement it, they form silicates with it or occupy the network between particles of quartz. In the latter case silica is considered a ''filler'' (e.g. porcelain clay bodies).
