摘要：
본발명은고순도·미세·구상이라는원하는성질을갖는탄산바륨입자를제조하는방법을제공하는것을목적으로한다. 본발명은 (A) 수성매체중에서, 바륨화합물과, 글루콘산및 그의염, 글루코노락톤, 글루코헵톤산및 그의염, 및글루코헵토노락톤으로이루어지는군으로부터선택되는적어도 1종의성분을혼합하는공정과, (B) 얻어진혼합물중에서, 상기바륨화합물에이산화탄소또는수가용성탄산염을반응시켜서대략구상인탄산바륨을얻는공정을포함하는, 대략구상인탄산바륨의제조방법에관한것이다.
摘要（中）：
本发明的一个目的是提供一种生产具有所需性能如高纯度，细小和球形的碳酸钡颗粒的方法。 在水性介质中，混合选自以下组成的组中选择的至少一种成分的钡化合物和葡糖酸及其盐，葡萄糖酸内酯，葡庚糖酸及其盐，和葡糖苷酶庚臀部内酯本发明（A） （B）使钡化合物与二氧化碳或水溶性碳酸盐在所得混合物中反应以获得近似球形的碳酸钡的步骤。
摘要（英）：
An object of the present invention is to provide a process for producing the barium carbonate particles having the desired properties of high-purity, fine, spherical. The present invention (A) in an aqueous medium, a barium compound and gluconic acid and salts thereof, glucono-lactone, glucoheptonic acid and salts thereof, and glucosidase heptyl buttocks lactone of mixing at least one component of selected from the group consisting of and in the process, (B) the mixture thus obtained, to a method of manufacturing a substantially spherical barium carbonate, which comprises the steps of obtaining a substantially spherical barium carbonate by reacting carbon dioxide or a soluble carbonate with the barium compound.
