Abstract

PURPOSE: To manufacture shpherical particles of tricalcium aluminate hydrate suitable for use as a filler for rubber, etc. by reacting Ca(OH)2 contg. a restricted amount of sucrose with Al(OH)3 in an aqueous suspended slurry.
CONSTITUTION: An Al(OH)3 slurry is added to a slurry prepared by adding 0.05W1.0pt.wt. of sucrose to 100pts.wt. of Ca(OH)2. The suitable Ca(OH)2 slurry is composed of about 5W150pts. Ca(OH)2 and 100pts. water, and the suitable Al(OH)3 slurry is composed of about 5W400pts. Al(OH)3 and 100pts. water. Ca(OH)2 is mixed with Al(OH)3 in about 3:2 molar ratio and reacted at ≥ about 95°C for ≥ about 2hr. The reaction product is filtered, washed, and dried to obtain spherical particles of tricalcium aluminate hydrate having ≤ about 10μm average particle size and about 2W3μm particle size distribution.
