  • Chromite Sand, Chromite Sand Manufacturers & Suppliers

    Chromite Sand is an oxide of Iron and chromium,Chromite Sand has a chemical composition FeOCr2O3. However, Chromite Sand conforming to theoretical composition is rarely found in the nature. Iron is found replaced by magnesium and similarly chromium by ferric iron and aluminum, thus bringing the composition..

    Chromite typically sells for about 2530% less than Zircon (comparing bulk prices of both types of sand). Chromite sand is black in color. So when you buy "heavy sand," make sure you are getting what you pay for. 1.00 pound of Chromite displaces 152cc vs. 295cc for Play Sand. So, that means Chromite is 94% heavier than an equal volume of Play Sand.
