Cristobalite Powder for Dental Investment Materials
Cristobalite powder for dental investment materials, produced from selected white quartz by calcination, grinding, filtration, drying and sieving. Review M3000–M6000 grades, whiteness 90–98 and the approved particle-size data for dental casting trials.
A Cristobalite Base for Dental Investment Materials
This grade is organized for dental investment-material preparation and evaluation. Selected white natural quartz is calcined, finely ground, filtered, dried and sieved before the powder is offered for review. The product page keeps the approved Cristobalite specification visible so a laboratory or purchasing team can compare the requested size against the same reference data.
Where the Dental Casting Grade Fits
- Dental investment-material preparation and formulation trials.
- Casting-flask workflows using wax patterns and investment molds.
- Comparison of M3000, M4000 and M6000 options against the required particle-size distribution.
- Sample planning based on the intended formulation, packing format and destination.
What to Confirm During a Dental Trial
Start with the investment-material recipe and the required mesh or particle-size range. Then review whiteness, chemical composition, density, moisture and the applicable particle-size row together. Trial observations should be matched to the buyer’s own mixing, setting and casting process.

Production Route for Dental Casting Cristobalite
The material route begins with manual selection of white natural quartz, followed by exterior water disposal, high-temperature calcination, fine grinding, filtration, drying and sieving. This description explains how the powder is prepared; final grade acceptance remains tied to the confirmed order specification and batch documentation.
Packing and Inquiry Information
- Standard packing: 25 kg bags, followed by 1000 kg bags where required.
- Container loading reference: 20–25 MT per 20-foot container.
- Custom packing can be discussed according to handling and delivery requirements.
- Share the dental use, target size, estimated quantity and destination for a sample or quotation.
