Premium Sintered Ceramic Sand, often referred to as "Golden Sand" or Cerabeads, is a high-performance artificial spherical grain engineered from calcined bauxite. Specifically designed for advanced foundry applications, this material consists primarily of aluminum oxide and silicon oxide, providing a superior alternative to traditional silica sand for high-precision casting requirements.
By utilizing a perfectly spherical morphology and high refractoriness, our Ceramic Sand optimizes the casting process by reducing thermal expansion and enhancing flowability. Whether used in lost foam casting, 3D printing, or precision casting, it ensures a smoother surface finish and higher structural integrity for cast iron, steel, and non-ferrous metals.

Ceramic Sand offers significantly higher refractoriness, lower thermal expansion, and a spherical shape, leading to better surface finishes and higher dimensional accuracy compared to silica sand.
Yes, as a neutral material, our Ceramic Sand is compatible with both acid and alkali resins, though we recommend monitoring the amount of binder addition for optimal results.
It is widely used in lost foam casting, coated sand, resin sand, cold core box, precision casting, and 3D printing for metals.
Ceramic sand is significantly lighter than zircon or chromite. This allows manufacturers to produce approximately twice the number of molds per unit weight, improving logistical and operational efficiency.
Absolutely. We offer a wide range of particle size distributions (from 45μm to 2000μm) and can customize the mesh size according to your specific technical requirements.
It is highly versatile and applicable for the casting of cast iron, cast steel, and various non-ferrous metals.
