• By the end of 1998 , minerals that had been discovered , confirmed and explored included : cyanite , silex ， quartz ， xanthoconite , others that need proving up and exploring included : mica , phosphorite , diamond , rutile , crude oil , kalium ore , etc
  至1998年底，发现、探明并已开发利用的矿种有：蓝晶石、硅石、石英砂、黄砂，有待探明和开发利用的矿种有云母、磷矿石、金刚石、金红石、石油、钾矿石等。
• The synthesized ti02 powders consist of anatase tio2 and rutile tio2 according to xrd patterns . results show that the ticfe particles show a mean grain size from 10nm to 50nm , and most of which present anatase . the content of anatase tio2 decrease with the increase of arc powder
  采用扫描电镜、透射电镜和x射线衍射仪分析了tioz颗粒的显微组织和晶型结构，计算了颗粒中的锐钦矿相和金红石相的含量与晶粒尺寸。
• It is pointed out that there exist abundant precambrian mineral resources in china , forming numerous large - superlarge iron , copper , lead , zinc , nickel , gold , ree , manganese , graphite , magnesite , talc , boron , phosphorus , pyrite , rutile and vermiculite deposits
  指出中国前寒武纪蕴藏著丰富的矿产资源，形成了众多的铁、铜、铅锌、镍、金、稀土、锰、石墨、菱镁矿、滑石、硼、磷、硫铁矿、金红石、蛭石等大型超大型矿床。
• With some proper conditions , the mixture of rutile and anatase phase powders could be obtained . the sizes of the powders increased in a relatively slowrate when the temperature was below 400 , but the size of the powders increased faster when the temperature is higher than 400
  在室温条件下制备了尺寸为9 . 7nm的金红石相， 9 . 2nm的锐钛矿相，以及混晶等多种二氧化钛纳米晶粉体，在400温度下煅烧可获得不同粒径的纳米晶粉体。
• Hence we combined coprecipitation method , using zinc carbonate as enclosure dose causing the crystal nucleus can not grow up , zinc titanate acts as phase - transition accelerant , thereby we can obtain rutile nanometer tio2 powder at lower calcining temperature and in briefer calcining time relatively
  因此我们结合共沉淀法，引入碳酸锌作包覆剂控制品粒长大，利用钛酸锌作品型促进剂，在相对较低的焙烧温度和较短的保温时间内制得到了金红石型纳米tio _ 2粉体。
• Rutile single crystal has been strongly interested because of its variability of physcal properties and particularity of photochemical characteristics afer it was artificially grown by c . h . moore in 1949 . it has been applied in opt - communication , solar light energy conversion and jewels
  Moore博士利用焰熔法首次人工合成了金红石单晶体以后，其多样的物理性质和独特的光化学性能逐渐被人们所认识，在宝石装饰、光通信以及光能转换等领域已经有了广泛的应用。
• Phase composition of nanometer tio2 is analyzed by x - ray diffraction , granule size and appearance of nanometer tio2 are analyzed by scanning electron microscope and transmission electron microscope , so we modified the conditions of experiment and obtained even and dispersive nanometer grade rutile tio2 powder that is spheric or oval - shaped
  通过x射线衍射、扫描电子显微镜、透射电子显微镜和原子吸收等检测分析研究，改进制备工艺条件，合成了粒度较均匀、分散性较好的球形或椭球形金红石型纳米级tio _ 2粉体。
