Kaist Ceramic Foundry Sand Powder, also known as Ceramic Foundry Sand Flour, is a high-performance refractory material specifically engineered with a particle size below 0.075 mm (under 200 mesh). Designed for precision and stability, this ultra-fine powder is either separated from sintered ceramic particles or customized for specialized industrial applications beyond traditional molding and core-making, offering exceptional refractoriness and thermal stability.
Engineered to meet the rigorous demands of modern metallurgy, this ceramic powder serves as a critical component in high-end foundry coatings and advanced 3D printing processes. By combining a spherical morphology with a high melting point and low thermal expansion, it provides a superior alternative to expensive materials like zircon sand flour, ensuring high-quality casting finishes and optimized production efficiency.

The primary difference is the particle size. Ceramic Sand Powder (or flour) has a particle size less than 0.075 mm (below 200 mesh), making it ideal for coatings and 3D printing rather than general molding.
Yes, it is designed for minimum reactivity towards many different kinds of metals, making it highly adaptable for various casting applications.
Its ability to be graded into a "single" mesh distribution ensures excellent flowability, which is critical for maintaining accuracy and quality in 3D printing.
Its excellent permeability and the fact that it requires lower binder addition reduce the release of gases during the casting process, thereby preventing gas holes.
The powder is versatile and can be applied through brushing, dipping, swabbing, or spraying, depending on the complexity of the mold.
Yes, it is an effective and more economical substitute that maintains high refractoriness and provides similar or superior results in foundry coatings.
