 * The material your are adding might be valid, but please use reliable sources - the reference your provide is commercial and dubious (doesn't cite any sources, apparently mixes up zirconia and zirconia TZP).
 * Further, when two administrators have reverted the same addition of yours and are explaining why it is problematic, it would be a very good idea to read, think, discuss, etc., but not to try reinstating your edits by brute force. Regards. Materialscientist (talk) 05:25, 12 May 2011 (UTC)
