    Detailed Description

    Chromite sand has established mounting awareness for several years, as a very effective moulding material for a multiplicity of different reasons:
    Low thermal expansion.
    High thermal conductivity.
    Good refractoriness.
    Efficient Substitute of Zircon Sand.
    General Description
    Chrome Spinel Sand
    Appearance and odour
    Chromite is a black sandy odourless material, which is free flowing when dry. It is insoluble in water and any common organic solvents
