THE PRODUCTION AND TECHNOLOGICAL DEVELOPMENT OF ELECTRONIC CERAMIC MATERIAL BARIUM TITANATE.

论述了电子陶瓷材料钛酸钡的生产工艺及技术进展，讨论了各种工艺的优缺点。

Barium is found in some oilfield brines in concentrations greater than 100mg/litre.

在有些油田卤水中，钡的浓度大于100毫克／升。

When an equivalent mole of Ba2＋ solution was added into the yellow solution, the precipitate produced was the peroxide precursor of barium titanate.

向该溶液中加入等摩尔的Ba2+溶液，制得了钛酸钡的过氧化物前驱体沉淀。

The process of production of Barium sulphate precipitated is

生产沉淀硫酸钡的工艺流程是

From the above instructions can see, chemical composition of barite powder and the chemical composition of Precipitation Barium sulphate is same, low content,But barite powder production process is simple,low cost.

从以上说明可以看出，重晶石粉和沉淀硫酸钡的化学成分是相同的，含量稍低，但是重晶石粉生产工艺简单，成本低。

And they also have great effect on the morphologies of the films.
