Abstract
The present invention is directed to a method of making metal oxide and mixed metal oxide particles. The method includes treating a mixture formed from a metal source, such as metal alkoxide, a surfactant, and a first alcohol in an aqueous media at a very high metal oxide yield. The mixture is reacted using a catalyst to form metal oxide particles having a desired particle size in said mixture. The method is particularly suitable for forming silica particles. The metal oxide particles can then be heat treated to form synthetic fused metal oxides such as, for example, synthetic fused silica.
