Coated abrasive material with abrasive grain mixtures containing alumina abrasive grain prepared by a sol-gel process

摘要

Coated abrasive material having blends of abrasive grains of sol gel alumina and alumina zirconia in a volume ratio of at least 15% sol gel abrasive grain provide better performance in certain grinding applications and a universally coated abrasive product for a wide range of grinding applications.
