ABSTRACT

In this study, amorphous aluminum silicate powder was prepared using co-precipitation method, and the influence of spray-dried aluminum silicate granular powder was analyzed and optimized by controlling the amount of aluminum silicate powder and dispersant added to the slurry. As a result, granular powder was optimally produced under the conditions of powder content of aluminum silicate slurry of 27.5 wt% or less, dispersant addition amount of 0.8 wt% or more, pH 6~9. An average particle size of granular powder showed approximately 14m at the powder contents of 20 and 22.5 wt% of the slurry, and approximately 19m at the powder contents of 25 and 27.5 wt% of the slurry.
