Ceramic Sand for 3D Printing

Short Description:

Sintered ceramic sand is mainly made of minerals containing Al2O3 and SiO2 and added with other mineral materials. A spherical foundry sand made by powder, pelletizing, sintering and grading processes. Its main crystal structure is Mullite and Corundum, with rounded grain shape, high refractoriness, good thermochemical stability, low thermal expansion, impact and abrasion resistance，features of strong fragmentation. When the ceramic sand applicated in 3D sand printing process, it can solve the silica sand fused problem, produce complex sand mold, increase the raw sand reused times, reduced waste sand emissions, improved casting yield.
