Item 7.01  Regulation FD Disclosure.

     On March 4, 2005, Douglas Ellsworth,  a Senior Vice President of the Altair
Nanotechnologies  Inc. (the  "Company"),  filed with the SEC a Form 4 reporting,
among other  things,  the sale on March 2, 2005 of 28,600  Common  Shares of the
Company in six (6)  transactions  subject to Section 16(b) under the  Securities
Exchange Act and rules promulgated  thereunder  ("Section 16(b)"). Mr. Ellsworth
had  previously  filed with the SEC Forms 4  reporting  the  acquisition  during
September  2004 of an  aggregate  of  7,500  Common  Shares  of the  Company  in
transactions  subject to Section 16(b).  The Company believes that the aggregate
profits,  calculated in accordance  with Section 16(b),  from such purchases and
sales  amount to $17,300 and are subject to the recovery  provisions  of Section
16(b).  Accordingly,  the Company demanded, and on March 21, 2005, received from
Mr. Ellsworth, a check in the amount of such profits and related materials.

     In light of this  event  and  separately,  as a result  of  certain  Form 4
filings  required under Section 16(a) of the  Securities  Exchange Act that were
filed  late,  the  Company is  developing,  an expects  to  promptly  implement,
additional  procedures with the goal of ensuring strict compliance by all of its
officers, directors and other persons subject to Section 16.
