氧化钡

Through the analysis of present status and existing problems of barium hydroxide production,the four measures for the production of barium hydroxide from witherite by hydrolysis method are put forward.

通过中国现有氢氧化钡生产现状及存在问题分析，对采用毒重石水解法生产氢氧化钡工艺提出了4项措施：增加毒重石矿选矿工艺，寻找新的毒重石矿源以提高品位，长时间研究确定生产工艺，开发氢氧化钡新的生产工艺线路。

From 93 to begin production barium hydroxide products so far, the company re-technology, and management is the production of "Pui-yu," licensing eight water barium hydroxide, a water barium hydroxide powder, a crystal water barium hydroxide, barium borate partial , barium carbonate, thiourea, and other products exported to the United States, Japan, Europe, South Africa, Southeast Asia, Taiwan, and other countries and regions.

从93年开始生产氢氧化钡产品至今，公司重科技、抓管理，现生产的"榆贝"牌八水氢氧化钡、粉体一水氢氧化钡、晶体一水氢氧化钡、偏硼酸钡、碳酸钡、硫脲等产品，远销美国、日本、欧洲、南非、东南亚、台湾等国家和地区。

Barium strontium titanate nanoparticles were successfully prepared by the low temperature (300-500℃) calcination method, using barium hydroxide, strontium hydroxide, and tetrabutyl titanate as starting materials.

以氢氧化钡、氢氧化锶和钛酸丁酯为原料，采用低温煅烧(300~500℃)法合成了钛酸锶钡纳米粒子。

I have eight main products plant water barium hydroxide, a water barium hydroxide powder, a crystal water barium hydroxide, barium borate partial, thiourea, barium carbonate, barium chloride, barium nitrate, after I plant refined products up to no chlorine, no sodium, low Sr, low iron.

我厂主要产品有八水氢氧化钡、粉体一水氢氧化钡、晶体一水氢氧化钡、偏硼酸钡、硫脲、碳酸钡、氯化钡、硝酸钡等，经过我厂精制的产品可达无氯、无钠、低锶、极低铁。

The presence of BaO affected the TPR performance of Co/SiO2, and Ba loading of 2% increased the reduction degree of Co/SiO2 at the moderate temperature (450℃). The difference of the TPR performance between unpromoted and promoted catalyst samples could be ascribed to the induction of the reduction of BaO, and the interactions between barium oxide and silica, barium oxide and cobalt oxide.

研究结果表明，氧化钡明显地影响Co/SiO2的还原性能；添加2%氧化钡提高了Co/SiO2在中温(450℃)条件下的还原度；氧化钡的还原对Co/SiO2还原的诱导、氧化钡与氧化硅及与氧化钴之间的相互作用是导致Co/SiO2还原性能变化的原因。

Barium nitrate products are mainly used in the manufacture of barium oxide, barium peroxide and other barium salt, also used in the manufacture of optical glass and pottery glaze, etc..

硝酸钡产品主要用于制造氧化钡、过氧化钡及其他钡盐，也用于制造光学玻璃和陶器釉药等。

The scandium oxide doped in the barium-calcium-aluminate 5BaO·3CaO·2Al2O3·0.6Sc2O3 compound is supposed to be a carrier for aarium oxide or barium atom which is the electron source, and it plays the role in controlling and roplonishing the electron source.

在掺氧化钪的发射物质5BaO·3CaO·2Al2O3·0.6Sc2O3中，氧化钪的作用则在于它和铝酸盐中的可利用氧化钡结合为2BaO·Sc2O3，成为电子发射源氧化钡或钡原子的载体，它起控制和补充发射源的作用。

Solubility of barium chloride and barium oxide in hydrochloric acid, ethanol,acetone,ether and hydrochloric acid- ethanol,hydrochloric acid- acetone,hydrochlo- ric acid- ether has beeen studied and the separation of Ba O from Ba Cl\- 2 with hydrochloric acidethanol as the solvent has been proposed.

研究了氯化钡和氧化钡在盐酸、乙醇、丙酮、乙醚及盐酸-乙醇、盐酸-丙酮、盐酸-乙醚中的溶解性，提出以盐酸-乙醇为溶剂进行两者的分离。以 DBC- CPA为显色剂分光光度法测定氧化钡的含量，加料回收率为 98%～ 10 2 %，氧化钡含量为 0 。32 %时，平行测定 7次，相对标准偏差为 1。 58%。该法适于快速测定热处理盐浴中氧化钡的含量，对监控盐浴品质有指导意义

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
