Dunite

Dunite alias Olivine Sand, As a foundry and refractory aggregate, Dunite is noted for its high fusionpoint, low uniform thermal expansion, and its remarkable ability to resistfracture from thermal shock. Olivine has been famous for years in producingexcellent non-ferrous castings, monolithic and basic refractoties and a key raw material for Manganese SteelCastings.. Today, more foundrymen are realizing that olivine works equally wellin Cast Iron and Stainless Steel.

Applications
- Refractory Sand, to manufacture manganese steel castings, and to form alloys
- Refractory Industry uses Olivine Sand for forming bricks and shapes, as it has a
high melting point, moderate thermal expansion, and stable crystalline structure.
- Temperature-loadable moulding sand and facing sand in foundry.
- Replacement of Garnet Sand for Shot Blasting.

- As EBT Tapehole Filler in Steel Plants for Electric Arc Furnace
