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.
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.
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 for solar-glass batch screening where the buyer must control iron, trace chemistry, particle-size distribution and melt behavior against a defined glass recipe. Grade selection follows the current TDS/COA and a customer melt trial.
Washed and graded natural crystalline quartz sand for resin-bound flooring, polymer concrete and controlled decorative-composite trials. Buyers should qualify grading, cleanliness, moisture, color and binder wet-out in the actual resin and installation process.
Washed and graded quartz sand aggregates for engineered stone slabs, offered in controlled size windows for packing, texture and surface design.
Technical Resources
Use practical guides to compare silica materials, convert mesh to microns and prepare clearer specifications for your application and RFQ.
Move a quartz filler comparison from beaker to pilot mixer with a decision matrix that separates material effects from scale-up effects.
Read flexural strength, impact, absorption, density, Mohs hardness and deep abrasion as separate results when qualifying a glass-filled slab trial.
Compare filler trials for low-crystalline-silica slab development by total cost per accepted area, while keeping phase evidence and slab qualification as separate gates.
