Zircon (zirconium silicate) sands are naturally occurring, rounded sands used in foundry, ceramic, refractory, and precision investment casting applications. They are critical components in the production of glazes, ladle brick, wall tiles, coatings, shell molds and cores, and metal chills.
Beryllium is a toxic bivalent element, steel gray, strong, light-weight, primarily used as hardening agent in alloys. Beryllium has one of the highest melting points of the light metals. It has excellent thermal conductivity, is nonmagnetic, it resists attack by concentrated nitric acid and at standard temperature and pressures beryllium resist oxidation when exposts to …
