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。

This Evaluate chronicles about twenty years of analysis into making a genetic code for crystal engineering. Rather than directing biological processes, this code utilizes artificial types of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which almost each facet of the resultant structures is usually systematically managed. Inside this conceptual framework, the structural and purposeful improvements are Crystal explained in an effort to determine the current volume of sophistication and to predict long term directions in the System.
Tetragonal �?Characterised by 3 mutually perpendicular axes, two of which can be equal in size, even though the 3rd is for a longer time or shorter and perpendicular to one other two.
