PRODUCTION OF SPHERICAL-SHAPED POROUS BASIC MAGNESIUM CARBONATE

摘要: PURPOSE:To produce a product with good dispersibility into water and organic solvent, easy to handle having workability by blowing gaseous CO2 starting suspension of basic magnesium carbonate while adding hydroxide allowing the mixture cause carbonation reaction. CONSTITUTION:The carbonatation reaction is started contained in tank suspension. The continued continuously Thereby, spherical-shaped porous uniform particle size produced without spreading distribution size. Then, concentration are preferably 10-80g MgO/l temp. system 40-80 deg.C.
