Natural rhodochrosite mineral raw materials teaching specimen
Prduct Knowledge
Rhodochrosite is a carbonate mineral, which often contain iron, calcium, zinc and other elements, and these elements tend to be replaced by manganese, therefore, pure rhodochrosite rare.
Rhodochrosite is a source of production of ferromanganese alloys manganese. They usually granular, massive or kidney-shaped, red, brownish black rear surface oxidation. It has a glass sheen.
Some colors look good and transparent rhodochrosite can be made into low-grade jewelry. Extract important ore mineral manganese. Large grain, transparent color the United States who can make gem; small particles, aggregates can be made translucent jade material
Morphology [rhodochrosite]
Trigonal; rhombohedral unit cell; arh = 0.584nm, α = 47.46 '; Z = 2; hexagonal unit cell: ah = 0.473nm, ch = 1.549nm; Z = 6. Calcite type structure. Complex tripartite scalenohedral crystal class, D3d-3m (L33L23PC). Crystal was rhombohedral-shaped, curved planes, mostly in the hydrothermal veins, but not common.
Main simplex: rhombohedron r, e, sometimes hexagonal column a, parallel-sided c. Hydrothermal who mostly was crystalline, granular, or columnar aggregates. Sedimentary origin who are mostly aphanitic, massive, oolitic, kidney-shaped, earthy and other aggregates.
Physical properties
Crystal pale pink or purple red, with the increased volume containing Ca, lighter color; dense block lanes are white, yellow, gray, brown or yellow, instead of when a Fe Mn, turns yellow or brown. Brown surface oxidation black. Shiny glass. Cleavage completely. Hardness of 3.5 to 4.5. Brittle. The relative density of 3.6 to 3.7.
Polarizing microscope: colorless or pale red roses. A crystal axis (-), No = 1.816, Ne = 1.597; refractive index with increasing amounts of Ca-containing decreases with increased Fe content increases.
Fragmentation shop sold rhodochrosite at 1-5.2 centimeters. Because it is a natural material, irregular shape, purity is not high, as is easily oxidized, so some will be with black oxide.
Our main minerals, rocks, fossils, semi-precious stones, etc all kinds of specimens as well as a variety of original rock of mineral raw materials, all kinds of stone crafts. Our products are from the original natural stone, so there are little differences between various stone, because nature is not a natural stone is the same.
