轴性、光性:一轴晶正光性。正交偏光下所看到的一轴晶干涉图是独特的,其黑十字臂未达中心,形成中空的图案,俗称牛眼干涉图。中心部分通常为淡绿色或淡粉色。

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。

Chemical Bonds The kinds of chemical bonds fashioned involving atoms or groups of atoms in crystals rely upon their size and electronegativity. You will discover four classes of crystals as grouped by their bonding:

Tetragonal: These crystals sort prisms and double pyramids. The construction is like a cubic crystal, except one axis is lengthier than one other.

C2 [ U ] clear glass of extremely top quality, usually with its surface area Slash into read more delicate patterns:

, has the identical framework, but There's two options for selecting the holes which the atoms will occupy. The 3rd layer is usually placed above the atoms of the very first layer, building an alternate layer sequence A

水晶原石观赏石,从字面意义理解:观赏水晶石的原貌,即经过抛光去皮后的包裹体水晶和原色水晶,不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高,水晶晶体通透干净,颜色艳丽,意境鲜明深刻的价值就高,它的价值特点就好比钻石,实实在在石头本身的价值。

发晶:无色、浅黄、浅褐等,可因含金红石常呈金黄、褐红等色,含电气石常呈灰黑色;含阳起石而呈灰绿色。

第三种是“皮景”,因某些其他的矿物与水晶体共生,或由于其他的物质侵蚀而依附于水晶表面,或者是水晶受自然环境的影响,在水晶表面出现蚀象,形成了一些景象或图案,这种景观存在于水晶表面。

幽灵水晶,分绿幽灵,红幽灵,白幽灵等,主要组成为绿泥石,其中绿幽灵属于珍贵品种。

15The trick to a very good thermoelectric substance is a crystal framework by which electrons can flow freely.制造一种好的热电材料的关键是,需要一种电子可以自由流动的晶体结构。

Crystallography will be the analyze of crystals, and it offers with all the things from perfect geometric shapes to seemingly random conglomerations of particles and minerals.

⑨、喷砂:立体感弱,较平整,无凹凸感,机器雕刻文字、图形等后进行效果处理。成本低制作快。

水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光,都可以在包裹体水晶种找到缩影。
