摘要：
Ooids, microabrasive compositions containing ooids and methods of making microabrasive compositions containing ooids are described. Generally, ooids represent small particles, which are selectable for size, size distribution, and other characteristics and can be used as a microabrasive particle. Ooids generally show a high level of symmetry, sphericity, roundness and a low aspect ratio. As described here, these characteristics generally yield a predictable and highly effective abrasive.
