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.
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.
Natural crystalline quartz sand processed from selected quartz stone for glass, ceramic and foundry formulations. Mohs hardness 7, milky-white to translucent appearance and particle-size grading available to agreed requirements. Contact Changtong for grade-specific chemistry, sizing, samples and quotation.
