Questions buyers ask
Short answers on purity, grades, applications and Certificates of Analysis.
What is the SiO2 purity of your quartz products?
SiO2 content varies with the source material, deposit, product grade and processing route. We do not represent all products as having one fixed purity level. Each commercial batch comes with a Certificate of Analysis showing the measured SiO2 content and relevant impurity levels.
Are your products semiconductor-grade or solar-grade?
No. Our standard processed quartz is industrial quartz feedstock, not finished semiconductor-grade or photovoltaic-grade material. Applications that need exceptionally low elemental impurities may require additional downstream purification and qualification by the end user.
Can your quartz be used to produce higher-purity silica?
Our material can be supplied as feedstock for further purification. The final purity you can reach depends on the starting material, its impurity profile and the downstream purification process.
What applications are your products suitable for?
Depending on grade and particle size: ceramics, glass, refractories, foundry, abrasives, engineered materials, filtration and other industrial applications. We also supply material to customers who purify it further.
Do you provide Certificates of Analysis?
Yes. Batch-specific COAs report SiO2 content, selected elemental impurities and physical characteristics such as particle-size distribution, depending on the product specification.
Can you supply to a customer’s specification?
Yes. We can discuss particle-size requirements, chemical specifications, packing and volume, and tell you whether we can supply a given specification consistently.
What should a request include?
The application, particle-size range, chemical limits with the analytical method, moisture limit, monthly volume, destination port and packing. The request form asks for each.
What is the minimum order?
One 20-foot container. We can discuss smaller trial quantities and samples before a first order.
How is your quartz priced?
We quote per specification. The price depends on the product and particle-size range, the chemical limits, the monthly volume, the packing, and the shipping terms: FOB Hambantota or CIF to your port. Send your specification and we reply with a quote.
Which shipping terms do you offer?
FOB Hambantota Port, Sri Lanka, or CIF to your destination port.
