根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：

The framework with the sodium atoms on your own, or even the chlorine atoms alone, is fcc and defines the unit cell. The sodium chloride composition Therefore is produced up of two interpenetrating fcc lattices. The cesium chloride lattice (Determine 3A) is predicated around the bcc construction; every single other atom is cesium or chlorine. In this instance, the device cell can be a cube. The 3rd vital composition for AB
Binary crystals are located in numerous constructions. Some pairs of click here aspects variety more than one framework. At place temperature, cadmium sulfide might crystallize both during the zinc blende or wurtzite composition. Alumina also has two feasible buildings at home temperature, α-alumina (corundum) and β-alumina. Other binary crystals show distinct buildings at distinct temperatures. One of the most sophisticated crystals are Individuals of silicon dioxide (SiO2), that has seven distinct structures at many temperatures and pressures; the most typical of such structures is quartz.
