2.The drying ability of fluorite is increased through the improvements of fluorite drying kiln,and as a result,the capacity of AHF plant in the company is expanded from 10 000 t/a to 15 000 t/a.
通过对萤石干燥炉等设备的改造 ,提高了萤石干燥系统的能力 ,为AHF装置的生产能力从 10 0 0 0t/a扩建至 15 0 0 0t/a提供技术保证。
3.It was shown that fluorite phase can formed at a relative low temperature when Al_2O_3 was doped into SDC. Al_2O_3-SDC powder with fluorite structure can be obtain at 600℃ by calcined the dried gel. The Al_2O_3-SDC powder has a nanometer particle(40~50 nm) with narrow particle size distribution.
实验研究结果表明,掺杂Al_2O_3的SDC电解质粉体成相温度低,干凝胶在600℃煅烧即可获得均匀的具有萤石结构的粉体,而且粉体的粒度较小(40～50nm),且粒度分布集中,粉末颗粒形貌基本呈球形,具有良好的烧结活性。
4.Wuyi is the hometown of fluorite for the large amount, high quality. Fluorite is also called as soft crystal because of its natural intrinsic quality.
武义有“萤石之乡”之称，产量多，品位高，质量好。萤石因其晶莹绚丽、玲珑剔透、天然多色，被宝石届誉为“软水晶”。
5.Don Edwards showed me some new Fluorite from a single pocket find at the Crich Quarry in Derbyshire - excellent for Derbyshire fluorite and, more unusually, fluorescent (possibly do to organic inclusions).
唐?爱德华兹从一个单独的袋子找出了一些德比郡克赖奇采石场新的萤石向我展示了，都是出色德比郡萤石，而更不寻常这些东西发萤光（可能含有有机包裹体）。
6.It has measured large numbers of large-middle scale deposits such as Fanshan alunite deposit of Cangnan county and Bamianshan fluorite deposit of Changshan county in Zhejiang province.
探明了浙江省苍南县矾山明矾石矿和浙江省常山县八面山萤石矿等一大批大中型矿床，曾获地质找矿二等奖1项，三等奖2项，四等奖多项。
7.A new processing method, gelation-flow-casting, specialized for the molding of polyvinyl fluorite (PVF) films, is introduced in this paper.
摘要介绍了一种适合聚氟乙烯薄膜生产制造的新工艺?凝胶挤出流延法。
8.The reserves of iron, barium, antimony, silver, fluorite, potash feldspar, white mica and other 20minerals are of a considerable scale.
