Product Description
This product is a high-purity crystalline silica powder specially optimized for precision casting (investment casting, lost-wax casting). Featuring ultra-fine particle size (adjustable D50 0.5-25μm), low thermal expansion coefficient, and excellent high-temperature stability, it significantly improves casting surface finish, dimensional accuracy, and reduces defects.
Applications
Precision Casting: Used in investment casting face coat to enhance surface finish
Ceramic Shells: Reinforces shell strength and reduces cracking
High-end Refractories: Low thermal expansion for high-temperature molds
3D Printed Casting: Additive for sand mold binders
Product Advantages
Ultra-fine Uniform Particles: Optimizes flowability for dense, defect-free coatings
High-Temperature Stability: Maintains structural integrity at 1600°C, minimizing shell deformation
Low Impurities: Strictly controlled metal content prevents casting contamination
Customizable Particle Size: Adaptable to various casting processes
Technical Highlights
• Reduces casting surface roughness
• Shortens dewaxing time and improves production efficiency
• Cost-effective performance when blended with zircon flour/bauxite
Packaging & Storage
25kg/bag (customizable)
Store in dry, cool conditions to prevent caking
