Schmelz Keramik Sand, technesch als "Sintered Keramik Sand fir Foundry" genannt, och als Ceramsite genannt, Cerabeads, Keramik, e puer Länner ass och Golden Sand genannt, ass eng gutt kënschtlech Kugelgestalt Form déi aus calcined Bauxit gemaach ass. Säin Haaptgehalt ass Aluminiumoxid a Siliziumoxid. Keramik Sand, huet vill besser Eegeschafte wéi déi vum Silica Sand fir eng besser Leeschtung an der Schmelz ze kréien. Et huet héich Refrakteritéit, wéineg thermesch Expansioun, gudde Wénkelkoeffizient, exzellente Flëssegkeet, Héich Resistenz géint Verschleiung, Kraaft an thermesch Schock, héich Erhuelungsquote.

Kaist ceramic foundry sand is about half as light as zircon and chromite, is about third as light as fused ceramic sand. Compared to these natural sand and other foundry media (the material is able to turn out about twice the number of molds per unit weight). Kaist ceramic foundry sand can deliver mold and core packages with a range of benefits that include higher-strength sand casting packages, with high heat resistance, low thermal expansion, improved final part resolution and a smoother surface finish. It can also be handled very easily, saving labor and transfer power costs. However, the manufacturer recommends paying attention to the amount of binder addition.
Als neutralt Material ass KAIST Keramik Sand applicabel fir Säure an Alkaliharzen.
Et kann wäit benotzt ginn fir Goss, Goss Stol an nonferro Metaller Goss, wéi verluer Schaum Guss, Beschichtete Sand, Harz Sand, kal Kär Këscht, Präzisioun Lous, an 3D Dréckerei.
