The QUARTZ Corp’s high purity quartz sand products are used widely in technical glass applications, serving the semiconductor, solar, optical fibre, and lighting markets, as well as in other demanding applications, such as laboratory glassware, bioactive glass, and EMCs.

Product list


Low alkali, ultra-high purity quartz sand with fine grain size. Ideal for use in flame fused semiconductor ingots, semiconductor crucibles, optical fibre preforms, and high end solar applications.


Low alkali, ultra-high purity quartz sand with coarse grain size. Ideal for use in electrically fused semiconductor ingots and large diameter crucibles.


Fine particle size product ideally suited for use in PV Czochralski crucibles, semiconductor ingots, and other technically demanding applications.


High intensity calcined product, offering good thermal stability in applications which require use at high temperatures for long duration.


Our workhouse product, ideally suited for use in Czochralski crucibles and large diameter quartz tubes and ingots.

Q4 Micro Range

A range of high purity quartz products with an ultrafine grain size and a carefully controlled narrow particle size distribution.


A standard particle size product suited for use in the outer layer of shorter-life Czochralski crucibles for the photovoltaic industry and for small and medium diameter quartz tubes.
