Where our quartz is used

Our quartz goes into industrial processes as supplied, or to customers who purify it further. We keep the two apart.

Industrial applications

Used as supplied, selected by particle size and the chemistry on the batch COA.

  • Unglazed ceramic tiles beside a bowl of white powder
    Ceramics
  • Stacked sheets of float glass seen edge-on
    Glass manufacturing
  • The polished edge of a white engineered quartz slab with grey veining
    Engineered stone
  • A clear column filled with layers of gravel and white sand
    Water filtration

  • Ceramics

    A main body and glaze component. Iron content affects the fired colour.

  • Glass manufacturing

    Silica is the main glass former. Clear and low-iron glass have strict iron limits.

  • Refractories

    High silica content and controlled impurities matter at high temperature.

  • Foundry

    Graded quartz for moulding and casting processes.

  • Abrasives

    Quartz is hard (Mohs 7), and crushed grains are angular.

  • Engineered stone

    Grits and powder make up most of the mass of quartz surfaces.

  • Water filtration

    Hard, chemically stable, graded media for filter beds.

  • Industrial fillers

    Fine powder as a functional filler in coatings, resins and compounds.

  • Construction materials

    Graded quartz where the product specification allows it.

Feedstock for further processing

Sri Lankan vein quartz can have naturally high SiO2 content. That makes it useful to customers who run their own purification, or who supply processors that do.

  • High-purity silica production
  • Crucible manufacturing feedstock, subject to further processing and customer qualification
  • Specialty glass
  • Optical materials, after purification and qualification by the customer

Advanced applications

Photovoltaic, optical and semiconductor supply chains need impurity levels far below industrial grades. Our material can enter these chains only as feedstock, after additional purification and qualification by the downstream manufacturer.
