Abstract
The invention is to processes for producing a nanoglass powder batches and to powder batches formed by such processes. In one embodiment, the process comprises the steps of providing a precursor medium comprising a first metal oxide precursor to a first metal oxide, a second metal oxide precursor to a second metal oxide, and a liquid vehicle; and flame spraying the precursor medium under conditions effective to form aggregated nanoglass particles comprising the first and second metal oxides, wherein the aggregated nanoglass particles have an average primary particle size of from 25 nm to 500 nm. The aggregated nanoglass particles preferably have an average aggregate particle size of from 50 nm to 1000 nm and may be amorphous or crystalline.
