METAL OXIDE PARTICLES AND METHOD OF PRODUCING THEREOF

摘要

Methods of producing high purity powders of submicron particles of metal oxides are presented. The methods comprise providing or forming an alloy of a first metal with a second metal, optionally heating the alloy, subjecting the alloy to a leaching agent to remove the second metal from the alloy and to oxidize the first metal, thus forming submicron oxide particles of the first metal. Collections of high purity, high surface area, submicron particles are presented as well.

主权项

1. A method of producing submicron metal oxide particles of one or more first metal(s), said method comprising:
providing or forming an alloy of said first metal(s) with a second metal; subjecting said alloy to a leaching agent effective to leach out said second metal and to oxidize said first metal(s), thus forming metal oxide submicron particles of said first metal(s); removing said leaching agent, leaving said metal oxide submicron particles of said first metal(s).
