中文百科
锆石
锆石(Zircon)，是天然矿物的一种，化学成份为硅酸锆(Zirconium Silicate, ZrSiO4)。锆石的化学成分为ZrSiO4。可含微量的Fe、Mn、Ca、U、Th等成分。由于U、Th等放射性元素的存在，可使锆石的结晶程度有不同程度的降低.锆石是一种硅酸盐矿物，它是提炼金属锆的主要矿石。锆石广泛存在于酸性火成岩，也产于变质岩和其他沉积物中。锆石的化学性质很稳定，所以在河流的砂砾中也可以见到宝石级的锆石。锆石有很多种，不同的锆石会有不同的颜色，如红、黄、橙、褐、绿或无色透明等等。经过切割后的宝石级锆石很像是钻石。锆石过去还被叫作锆英石或风信子石。锆石，可以耐高温的，温度可以达到3000℃以上的高温。一般首饰类耐高温度750℃-1250℃。
英语百科
Zircon 锆石
Zircon (/ˈzɜːrkɒn/ or /ˈzɜːrkən/; including hyacinth or yellow zircon) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate and its corresponding chemical formula is ZrSiO4. A common empirical formula showing some of the range of substitution in zircon is (Zr1–y, REEy)(SiO4)1–x(OH)4x–y. Zircon forms in silicate melts with large proportions of high field strength incompatible elements. For example, hafnium is almost always present in quantities ranging from 1 to 4%. The crystal structure of zircon is tetragonal crystal system. The natural color of zircon varies between colorless, yellow-golden, red, brown, blue, and green. Colorless specimens that show gem quality are a popular substitute for diamond and are also known as "Matura diamond".
