当人们步入地质博物馆展厅时,到处都可以看见五彩缤纷、光耀夺目,晶莹透澈的各种各样的矿物。这些矿物的不同颜色究竟是怎样产生的呢?经过矿物学家研究表明:大多数矿物的颜色都是由色素离子的存在造成的。一是矿物固有化学组分中色素离子所引起的;另一种情况是,矿物本来是无色的,颜色是由其它微量元素色素离子混入而引起的。我们看到矿物的颜色是矿物块体、晶体表面所表现的颜色,并不是矿物本身的粉末颜色,它所表现的是入射光波能量被矿物部分地吸收后,再反射的光量和光色。带有颜色的矿物不一定全能制成颜料。在3300多种矿物中,能制
When people walked into the Geological Museum exhibition hall, everywhere you can see a colorful, shining, crystal clear variety of minerals. How are the different colors of these minerals produced? After mineralogist research shows that: most of the mineral color is caused by the presence of pigment ions. One is caused by pigment ions in the chemical components of the mineral; the other is that the mineral is originally colorless and the color is caused by the mixing of other trace element pigments. We can see that the color of mineral is a mineral block. The color of the crystal surface is not the color of the powder itself. It shows the amount of light and the color of light reflected by the incident light wave partially absorbed by the mineral. Colored minerals are not necessarily all-made pigments. In 3300 kinds of minerals, can system
