<p>[QUOTE=&quot;desertgem, post: 1534452, member: 15199&quot;]As with all supply/demand scenarios, most ignore incoming alternatives. As long as platinum , palladium, etc, were &quot;relatively&quot; cheap ( lets say below $800-1000) there was little push to find alternatives, but after the large rise in price and inconsistent supplies, alternatives are being developed, after all catalysts are a chemical entity and not limited to just one element. here is a recent blurb about using silicon carbide crystals as a replacement for platinum. Our knowledge of silicon carbide chemistry has increased tremendously. It can be synthesized into synthetic moissanite ( more sparkle than a diamond, more heat resistant, hardness of&nbsp; 9 - 9.5 ( diamond is 10). fairly large size. </p><p><br /></p><p>Don&#039;t think that demands of industrially used metals will remain high, as new expertise will focus or cheaper and more readily available substances.</p><p><br /></p><p><br /></p><p><a href="http://www.dailykos.com/story/2010/01/02/820517/-Superatoms-Cheap-replacements-for-Platinum-and-Palladium" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.dailykos.com/story/2010/01/02/820517/-Superatoms-Cheap-replacements-for-Platinum-and-Palladium" rel="nofollow">http://www.dailykos.com/story/2010/01/02/820517/-Superatoms-Cheap-replacements-for-Platinum-and-Palladium</a>[/QUOTE]</p><p><br /></p>
