FREMGANGSMAADE TIL FREMSTILLING AF BARIUMSULFAAT MED KEMOREAKTIV OVERFLADE |
摘要 |
<p>There is described a process for preparing barium sulphate having a chemically reactive surface by precipitating barium ions in an aqueous medium by means of sulphate ions. …<??>To make barium sulphate available as a filler having functional properties, the precipitation, or coprecipitation, is carried out in the presence of additional anions of water-soluble compounds which are precipitable with barium ions and form sparingly soluble barium compounds therewith. …<??>The product, which contains foreign ions and is reactive, is subjected to a suitable aftertreatment for whichever particular use is envisaged.</p> |
