ULTRA HPQ QUALITY

 

Ultra HPQ high purity quartz sand is engineered for the manufacture of quartz crucibles which are intended for use in the Czochralski process to produce silicon ingots for subsequent wafering, processing and assembly into photo-voltaic solar panels.

Ultra HPQ high purity quartz sand has been independently and rigorously tested to validate its quality and suitability for the manufacture of high purity quartz crucibles.  This independent testing has shown that,

    • Ultra HPQ high purity quartz sand shows good melt characteristics with levels of bubbles similar to commonly used high purity quartz sands from Spruce Pine
    • Ultra HPQ high purity quartz sand has typical levels of impurities similar to commonly used high purity quartz sands from Spruce Pine, and can have lower contents of some critical elements such as alkali metals.

Ultra HPQ high purity quartz sand can also be used for the manufacture of quartz glassware which can then be used in the processing of silicon wafers for solar or semi-con applications, or in the manufacture of quartz glass lighting tubes.

Ultra HPQ high purity quartz has also been tested for use in high performance epoxy moulded compound where levels of Uranium and Thorium are critical, and has been found to easily meet requirements.
