Thermal Expansion of Chemically Bonded Silica Sands · Fichier PDF

of silica sand's abrupt thermal expansion and unstable crystal phases, dimensional accuracy of castings produced in these materials is compromised. Zircon, chromite, and various mullite ceramic aggregates are being chosen to replace silica in high accuracy castings because of their low thermal expansion and dimensional stability. Fortunately, silica sand still has a place in producing highly ...
