Definition of silicate in English:



  • 1A salt in which the anion contains both silicon and oxygen, especially one of the anion SiO₄²−

    • ‘The weathering of calcium silicate rocks over millions of years converted the insoluble calcium silicate into soluble calcium salts, which were carried to the oceans.’
    • ‘The most significant user is the glass industry, which uses sodium carbonate to decompose silicates for glass making.’
    • ‘By sharing two oxygen atoms, silicates can form either cyclic or chain structures.’
    • ‘Silicon is the second most abundant element in the Earth's crust, since most common rocks have crystalline frameworks made from silicon and oxygen: they are silicates.’
    • ‘Certain salts, such as the dichromates, borates, and silicates, act as inhibitors to the aqueous corrosion of zinc.’
    1. 1.1Any of the many minerals consisting primarily of SiO₄²− combined with metal ions, forming a major component of the rocks of the earth's crust.
      • ‘Montmorillonite is a swelling clay formed from the degradation of silicates such as feldspars, volcanic minerals, chlorite and illite, and is commonly found in alkaline soils today.’
      • ‘Those plants obtain various minerals and silicates from earth in their bodies during growth process.’
      • ‘Soil typically includes an organic plant layer, topsoil and layers of minerals, silicates, clay and parent materials.’
      • ‘With the exception of quartz and the feldspars, few common rock-forming silicates are available in fine, collectible specimens on a regular basis.’
      • ‘Instead, silica is found in polymerized combinations with metals as silicates embedded in geologic rock formations, such as quartz.’
