Calcite crystals are sometimes Utilized in optical gear, as well as the graphite in pencil guide are sheets of crystals that fundamentally split aside layer by layer to put in writing. Silica can form silicate crystals which might be the basis for quartz, mica, olivine, and all kinds of other crystals and minerals.
无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度,越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏,就没有利用价值。
晶及其石英岩类玉石是中低档宝玉石,虽比不上钻石、红蓝宝石的高贵,但在加工中如果构思巧妙而且加工精细,同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
养殖晶:养殖晶是指,用天然水晶做种子,然后赋予天然水晶生长的高压条件,养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长,这样的水晶成分(分子式)与天然水晶是一摸一样的,唯一有差别的是,这样的水晶磁场作用没有天然水晶强。
断口:贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂,破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
These examples are from corpora and from sources on the internet. Any viewpoints during the examples don't characterize the opinion in the Cambridge Dictionary editors or of Cambridge College Press or its licensors.
⑦、镀彩:运用类似电镀的手法在水晶表面以不同的色彩,层面较薄,经摩擦可划伤�?;出现划痕,由于镀彩经常位于底部,因此在镀彩底部经常采用其它对象附着,如生肖文镇。
The weather are discovered in a number of crystal packing preparations. The commonest lattice structures for metals are These received by stacking the atomic spheres into quite possibly the most compact arrangement.
水晶常以晶簇、晶洞形式产出,其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙,当富含硅质矿物的流体进入较薄的熔岩孔隙中,且温、压条件合适时将结晶沉淀出水晶等矿物。
[ C/U ] transparent glass of high quality, ordinarily with its floor Slash into patterns that mirror light
. The 2nd layer is shaded in the determine. It has the same plane-triangular composition; the atoms sit while in the holes shaped by the 1st layer. The 1st read more layer has two equivalent sets of holes, however the atoms of the second layer can occupy just one established. The third layer, labeled C
Crystallography is definitely the examine of crystals, and it bargains with every thing from excellent geometric designs to seemingly random conglomerations of particles and minerals.
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟,喜欢将它们摆在家里或办公室里,认为水晶球有灵性,能保平安,带来财运。不过天然水晶不像看起来那么晶莹剔透,它也有瑕疵,我们在选购饰品的时候要注意。此外,我们还要掌握水晶的评价依据、选购方法,这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
矿物成分:针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶,如发晶、钛晶、绿幽灵等,发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶;含铁�?;呈金黄色或柠檬�?)称黄水晶;含锰和钛呈玫瑰色者称蔷薇石英,即粉水晶;烟色者称烟水晶;褐色者称茶晶;黑色透明者称为墨晶。
