METHODS OF MAKING CERAMICS COMPRISING AL2O3, REO, ZRO2 AND/OR HFO2 AND NB2O5 AND/OR TA2O5

摘要

Methods for making glass-ceramics comprising Al2O3, REO, at least one of ZrO2 or HfO2 and at least one of Nb2O5 or Ta2O5. Glass-ceramics according to the present invention can be made, formed as, or converted into glass beads, articles (e.g., plates), fibers, particles, and thin coatings. Some embodiments of glass-ceramic particles according to the present invention can be are particularly useful as abrasive particles. ® KIPO & WIPO 2007
