①压电效�?在机械力(压力或拉�?作用下，水晶单晶体的两端会产生电荷，其电量相等但符号相反。在工业上，无色、无缺陷、不具双晶的水晶常被用来作压电石英片。
天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。
Substantial crystals of diamond are valuable gemstones. The crystal has other fascinating Houses; it's got the very best audio velocity of any good and is the best conductor of heat. Aside from diamond, one other popular type of carbon is graphite, which can be a layered substance. Each carbon atom has a few coplanar close to neighbours, forming an arrangement called the honeycomb lattice. A few-dimensional graphite crystals are obtained by stacking comparable layers.

There are actually only a few distinct unit-cell styles, so many alternative crystals share only one unit-cell variety. A very important attribute of the unit cell is the amount of atoms it is made up more info of. The entire quantity of atoms in the entire crystal could be the quantity in Every single mobile multiplied by the number of unit cells. Copper and aluminum (Al) Each individual have just one atom per unit cell, when zinc (Zn) and sodium chloride have two. Most crystals have only some atoms per unit mobile, but usually there are some exceptions. Crystals of polymers, by way of example, have A huge number of atoms in Just about every device mobile.
