seeded gel aluminum oxide abrasive grain F36 F46 F54
Introduction of seeded gel aluminum oxide abrasive grain F36 F46 F54
Sol-Gel Alumina abrasive is a new type abrasive grain totally different from traditional fused alumina. Sol-Gel is also called ceramic alumina grain,it is made by sol-gel process.
α-Al2O3 micro-crystal always added as seed into the raw mixed materials of Al2O3 H2O micropowder and water. By doing so,crystal will get more compact when calcined to get solid sol-gel grains. The calcining and sintering process are very important to make sol-gel crystal get small α-Al2O3 crystal size.
