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.
Silane-treated silica powder for industrial sealant and adhesive formulations. The treated mineral surface is designed to improve filler wetting and compatibility in selected organic binder systems, while controlled particle-size options support practical mixing. Confirm treatment chemistry and test requirements against the customer’s polymer and cure process.
Active silica powder made from selected natural quartz through fine grinding, classification and hydrophobic surface activation. It is intended for polymer masterbatch, resin and specialty compound formulations where water repellency, low oil absorption, low viscosity build, high dispersion and resin compatibility are important. Final performance depends on the treatment level, resin polarity, loading and mixing conditions.
Surface-treated natural quartz filler for EV module encapsulation resin trials. Confirm moisture, PSD and resin compatibility before selecting a grade.
Calcined quartz powder for enamel glaze systems on metal and glass. Customer-side comparison reports reviewed 200 and 325 mesh residue, SiO2, Fe2O3 and an 8% glaze addition trial; final grade selection must be confirmed against the frit, substrate and firing process.
Cristobalite powder for enamel frit and ceramic glaze formulations, processed from selected natural quartz through controlled calcination, grinding, classification and sieving. Grade, phase evidence, particle-size distribution and chemistry should be confirmed against the customer’s frit, glaze and firing process.
Evaluate fused silica powder for refractory castables. Confirm particle size, lot documents, binder compatibility and thermal-cycle requirements before sampling.
M4000 calcined cristobalite powder for silicone rubber and selected industrial rubber compounds. The supplied batch report records D50 6.15 μm, SiO2 99.63%, Fe2O3 0.009%, moisture 0.1% and whiteness 94%. Final loading and performance must be qualified in the customer's polymer, filler and cure 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.
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.
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.
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.
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.
Technical Resources
Use practical guides to compare silica materials, convert mesh to microns and prepare clearer specifications for your application and RFQ.
Separate cristobalite powder whiteness from coating hiding power. Compare controlled films, black and white backgrounds, and a clear formulation basis.
Evaluate cristobalite-filled silicone with matched tear specimens, cure history and loading. Keep hardness, tensile and service-tear claims separate.
When a high SiO₂ assay still coincides with bubbles in fused quartz, qualify the sand with a defect-to-evidence chain that extends beyond bulk chemistry.
