　　最近有很多热心网友都十分关心钻石的硬度有多硬（钻石的硬度）「知识普及」这个问题。还有一部分人想了解钻石的硬度有多硬。对此，和记百科小编「甜心奶泡」收集了相关的教程，希望能给你带来帮助。

钻石的硬度

　　钻石的摩氏硬度为10。是自然界中硬度最大的物质，是在地球深部高压、高温条件下逐渐形成的一种由碳元素组成的单质晶体。绝对硬度是石英的1000倍，刚玉的150倍，怕重击，重击后会顺其解理破碎。

　　钻石的特征：

　　晶体形态多呈八面体、菱形十二面体、四面体及它们的聚形。纯净的钻石无色透明，由于微量元素的混入而呈现不同颜色。强金刚光泽。折光率2.417，色散中等，为0.044。均质体。热导率为0.35卡/厘米/秒/度。用热导仪测试，反应最为灵敏。钻石具有发光性，日光照射后 ，夜晚能发出淡青色磷光。X射线照射，发出天蓝色荧光。钻石的化学性质很稳定，在常温下不容易溶于酸和碱，酸碱不会对其产生作用。

钻石的硬度有多硬

　　10

　　钻石是指经过琢磨的金刚石，金刚石是一种天然矿物，是钻石的原石。简单地讲，钻石是在地球深部高压、高温条件下形成的一种由碳元素组成的单质晶体。钻石是目前世界上已知的最硬的一种自然物质。钻石产量稀少，通常为无色晶体，具有高度的折光特性，能折射出多彩的光泽。钻石不仅可以用作首饰，工业上也用来作为高级的切削和研磨材料。

　　【英文介绍/For English】：

　　Diamonds have a Mohs hardness of 10. It is the hardest substance in nature, and it is a kind of elemental crystal composed of carbon element which is gradually formed under the conditions of high pressure and high temperature in the deep part of the earth. The absolute hardness is 1000 times that of quartz, and 150 times that of corundum.

　　Characteristics of a diamond:

　　The crystal forms are mostly octahedron, rhombic dodecahedron, tetrahedron and their aggregates. Pure diamonds are colorless and transparent, showing different colors due to the mixing of trace elements. Strong diamond luster. The refractive index is 2.417, and the dispersion is medium, which is 0.044. Homogeneous body. Thermal conductivity is 0.35 cal/cm/sec/degree. Tested with a thermal conductivity meter, the response is the most sensitive. Diamonds are luminous and emit a pale cyan phosphorescence at night when exposed to sunlight. When irradiated by X-rays, it emits sky blue fluorescence. The chemical properties of diamond are very stable, and it is not easy to dissolve in acid and alkali at room temperature, and acid and alkali will not have any effect on it.
