摩氏硬度表 Mohs Hardness Scale摩氏硬度表Mohs Hardness Scale 摩氏硬度计矿物的硬度是指矿物抵抗外来机械作用力(如刻画、压入、研磨等)侵入的能力。早在1822年,Friedrich mohs提出用10种矿物来衡量世界上最硬的和最软的物体,这是所谓的摩氏硬度计。按照他们的软硬程度分为十级:1、滑石6、正长石2、石膏7、石英3...

Mohs' (hardness) scale [ A standard of ten minerals by which the hardness of a mineral may be rated. The scale includes, from softest to hardest and numbered one to ten: talc; gypsum; calcite; fluorite; apatite; orthoclase; quartz; topaz; corundum;, and diamond ] ● Mohssche (Hrte-)...
The original Mohs scale is as follows: Hardness Material Absolute Hardness 1 Talc (Mg3Si4O10(OH)2) 1 2 Gypsum (CaSO4·2H2O) 3 3 Calcite (CaCO3) 9 4 Fluorite (CaF2) 21 5 Apatite (Ca5(PO4)3(OH-,Cl-,F-)) 48 6 Orthoclase (KAlSi3O8) 72 7 Quartz (SiO2) 100 8 To...
The Mohs Hardness Scale is a standard that indicates the hardness of minerals. It was first proposed by German mineralogist Frederich Mohs in 1822.
MohsHardnessScale
Mohs scale (mōz) n. A scale for classifying minerals based on relative hardness, determined by the ability of harder minerals to scratch softer ones. The scale includes the following minerals, in order from softest to hardest: 1. talc; 2. gypsum; 3. calcite; 4. fluorite; 5. apatite; ...
: a scale of hardness for minerals in which 1 represents the hardness of talc; 2, gypsum; 3, calcite; 4, fluorite; 5, apatite; 6, orthoclase; 7, quartz; 8, topaz; 9, corundum; and 10, diamond 2 : a revised and expanded version of the original Mohs' scale which provides finer ...

10 gemstones that represent the most common gemstone families (talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and diamond) and set about scratching them against each other, until he was able to develop a hierarchy of scratchability - theMohs hardness scale. ...
