PREPARATION OF GRANULAR COMPOSITIONS |
摘要 |
A process for preparing granular water soluble alkali metal borate compositions by agitating a finely divided feedstock comprising a water soluble alkali metal borate and optionally boric acid, the molar ratio of alkali metal oxide to boric oxide in the feedstock being from about 0.1 to 0.5:1, optionally heating the agitated feedstock particles, contacting the agitated feedstock particles with an aqueous granulating agent to agglomerate feedstock particles, and recovering a granular borate composition having an average particle size of at least 250 micro meters. The resultant granulated product has a higher bulk density and better water dissolution rate than the feedstock particles.
