Preparation and Investigation of BaS0,-KMnO, Crystals BaSO, crystals containing KMnO, prepared by precipitation were investigated morphologically, chemically and by X-ray diffraction. The colour of the preparations is homogeneous and stable. The colour intensity and also the amount of dissolved KMnO
In order to influence the habit of barite (BaS04) single crystals obtained by precipitation, the tailor-made additives 2-aminoethanol, 3-aminopropanol, 5-aminopentanol, 4-aminobutane sulfonic acid, and several other growth inhibitors have been tested. The crystallization experiments have been carrie
The effect of supersaturation, reaction temperature, and mixing intensity on particle size was investigated. Sterical stabilization of barium sulfate suspensions was applied to prevent formation of agglomerates. This allowed a reactant ratio of 1:1, thus maximizing product yield. The local supersatu
