  • Difference Between Quartz Calcite Sciencing

    Apr 24, 2017  Calcite is made of calcium carbonate, a compound containing calcium, carbon and oxygen atoms. Quartz is silicon dioxide, a chemical compound with one atom of silicon and two atoms of oxygen.Quartz is much harder than calcite. Quartz reaches 7 on the Mohs scale of mineral hardness, whereas calcite's hardness is 3.

  • Physical Properties of Calcite Quartz Sciencing

    Calcite is a polymorph of calcium carbonate, meaning that it is one of many crystalline forms of calcium carbonate (argonite would be another), whereas quartz is a polymorph of silicon dioxide.Both mineral crystal structures fall under the trigonal-crystal-shape category, though calcite differs slightly in that it exhibits a rhombohedral lattice structure.
