Altair Nanotechnologies Announces
New Australian Patent Award Notification

Patent Protects Basic Technologies for Commercial Development
Programs of Nano-Sized and Pigment-Sized Ti02


RENO, NV -- (MARKET WIRE) -- 01/25/2005 -- Altair Nanotechnologies, Inc. (NASDAQ: ALTI) announced today that it was awarded a new Australian patent covering "Processing Aqueous Titanium Solutions to Titanium Dioxide Pigment" by the Australian Patent Office.

The new patent describes the fundamental technology for a hydrometallurgical process for producing pigment-grade titanium dioxide ("Ti02") containing solutions. The process includes hydrolyzing the solution via complete evaporation in controlled conditions of temperature to form titania oxide of defined characteristics. After hydrolyzing, the titanium oxide is calcined to form either anatase or rutile pigment of the desired particle size. It is then milled for final processing.

"Our patented process provides significant economies of scale and considerable environmental advantages over the existing chloride and sulfate processes," commented Altair Nanotechnologies CEO Dr. Alan J. Gotcher. "Further, our manufacturing process provides for an environmentally friendly method for pigment companies to streamline operations and reduce costs."

The new patent follows the award of two other patents covering the environmentally friendly process for TiO2 pigment production, an $8 billion industry. Altair's patent portfolio includes: 1) Processing Titaniferous Ore to Titanium Dioxide Pigment; 2) Processing Aqueous Titanium Chloride Solutions to Ultrafine Titanium Dioxide, and 3) Processing Aqueous Titanium Solutions to Titanium Dioxide Pigment.

Over the past five years, Altair has expended significant resources to pioneer and develop advanced ceramic nanotechnology and currently owns six U.S. Patents and 12 foreign patents with 46 additional pending U.S. and foreign patent applications. Altair is aggressively pursuing licensing and business development programs utilizing its technology, nanomaterials and nano-based products worldwide.
