摘要：
Free flowing, substantially dust-free, dense granular amorphous precipitated silica having a principal particle size of between about 0.14 millimeters and about 0.84 millimeters are described. This material is particularly suitable as an inert carrier for water-soluble and fat soluble nutritional supplements, e.g., vitamins, which are added to feeds for livestock.
