Product category: Silica sand

Fused Silica

Fused silica is an amorphous siliceous glass produced by high temperature fusion of high quality crystalline silica (quartz). This fusion produces a substance characterised by very low thermal expansion and a high resistance to temperature and thermal shock.

Fused silica is employed in a variety of industrial applications including foundry (investment casting slurry and stucco, and mould release agent), refractory and ceramic (crucibles, saggars, rollers, pouring cups, ceramic cores, gas fire radiants and items for steel, nonferrous metal and glass industries), and filler (electronic and adhesives). Dupré Minerals realised early on that the secret of manufacturing investment powder lay in the quality of the raw materials available.

The company has carried out an extensive global sourcing project and has located what it considers to be some of the highest quality refractories so far made available to investment foundries. These include Fused Silica produced from quartz of exceptional purity with an SiO2 content of 99.9%. The source also has particularly low iron, potassium and sodium oxides and such a low trace element content to fall well within Aerospace specifications.

Product category: Zircon sand and flour

Zirconium Silicate

The highest purity Zircon or Zirconium Silicate can be found in deposits close to the American, Australian and South African coasts. Zircon sand is separated from other minerals by ore dressing techniques during which strict controls are made to ensure the quality of the final product.

Depending on the application, Zircon sand may be calcined at a high temperature giving a stabilised product.

At one of the most sophisticated plants in Europe, Zircon is processed and milled to the most stringent grading and particle sizes required.

A range of Zircon materials is available. However, for special applications, alternative particle sizes can be processed.
