Spherical mullite ceramic sand

Description

3D Printed Ceramic Sand — Product Features & Advantages: 1. Low thermal expansion reduces casting deformation and improves surface quality; 2. High refractoriness, excellent thermochemical stability, low volatile content, resistant to sand adhesion and veining defects; 3. Spherical and dense particles with low angularity, smooth surface, and good flowability, requiring less resin, generating low gas, easy to fill, and offering good permeability to reduce porosity defects; 4. Appropriate and uniform strength with low high-temperature residual strength for easy removal; 5. High sintering point, excellent high-temperature durability, and low sand burn-on; 6. Resistant to thermal shock, low breakage rate, and high recycling/reclamation rate; 7. Fewer casting defects and lower rejection rates, reducing machining and overall casting costs.
