  • Angular ceramic particles and methods of making and using same
    Patent number: 11673836
    Abstract: The present disclosure provides processes for forming angular ceramic particles. In at least one embodiment, a process for forming angular ceramic particles includes providing a slurry having a ceramic raw material having alumina. The process includes atomizing the slurry into droplets and coating seeds comprising alumina with the droplets to form green pellets. The process includes sintering the green pellets to form sintered pellets. The process includes breaking the sintered pellets to form the angular ceramic particles comprising a sintered ceramic material. The angular ceramic particles can have an abrasion loss that is less than that of angular ceramic particles formed by crushing the green pellets prior to sintering.
