Silica Material Portfolio
Compare crystalline silica powder, fused silica powder and sand, cristobalite, ultrafine silica and surface-treated silica for industrial applications.
PRODUCT FAMILIES
Start with the material family that matches your process, then compare grades, particle sizes, properties and applications.
Crystalline silica powders for coatings, silicone rubber and electronic packaging.
Low-expansion fused silica powders, sand and granules for casting, refractory and ceramics.
High-whiteness cristobalite flour, powder and sand for casting, coatings and engineered compounds.
Clean quartz raw material and refined particles for purity-sensitive industrial applications.
Refined translucent and porcelain-white quartz sand grades for casting, ceramics and refractory uses.
Precision quartz rods, plates and engineered quartz components for technical applications.
Fused silica powder for refractory gunning mix trials where phase identity, particle-size control and process compatibility must be evaluated together. Confirm grade-specific chemistry, PSD, moisture and application fit against the customer’s mix and spraying conditions.
Fused silica powder for EV inverter and power-module epoxy potting trials where low expansion and dimensional stability are required. Match purity and PSD to viscosity, vacuum filling, thermal cycling, dielectric strength and partial-discharge acceptance in the customer’s resin system.
M4000 calcined cristobalite powder for EV high-voltage silicone cable compound trials. A supplied batch reports D50 6.15 μm, SiO2 99.63%, Fe2O3 0.009%, moisture 0.1% and whiteness 94%; qualify dispersion, cure, electrical insulation and finished-cable performance in the customer’s formulation.
High-whiteness cristobalite powder for cool-roof and reflective architectural coating trials. M3000/M4000/M6000 reference grades provide D50 options of 12/5/3 μm; confirm dispersion, solar reflectance, thermal emittance, SRI and weathered retention in the finished coating.
Low-expansion fused silica powder for semiconductor epoxy molding compound screening in advanced packaging. Reference chemistry includes SiO2 >99.90% and Fe2O3 <50 ppm; select PSD and purity against filler loading, flow, warpage, ionic contamination and package-reliability targets.
Graded natural quartz sand for terrazzo, decorative stone and resin-bound surface formulations. Confirm particle size, color, chemistry and application fit against the project specification and trial.
Crystalline silica powder for tile adhesive and grout formulations, with controlled grading for dry-mix workability, filler packing and consistent joint texture. Confirm grade-specific data with Changtong.
Calcined PV silica powder prepared for shoe mold and related precision mold-making processes where consistent mineral chemistry, hardness and powder control matter.
High-purity fused quartz sand for electrical insulation compounds and refractory formulations. Amorphous silica with low thermal expansion, controlled granular grades and multiple particle-size options for application-specific evaluation.
Natural-quartz-derived surface-treated powder for epoxy flooring formulations. Intended for controlled comparison of hydrophobic response, filler wetting, dispersion, oil absorption and viscosity build; final performance must be validated in the customer's resin and flooring system.
Fused silica powder for electrical epoxy casting and vacuum-cast insulation component trials. Grade selection should be matched to the resin, target particle-size distribution, filler loading, mold-filling process, cure schedule and the buyer's finished-component tests.
High-purity 1–3 mm fused silica granules for refractory, ceramic, foundry and investment-casting applications, with low thermal expansion, strong thermal stability and controlled granular form.
