The disclosure relates broadly to a new class or type of electroconductive powders (ECP), designated as Polytype ECP (PECP), comprising intimate mixtures of several types of ECP powders. PECP mixtures possess a lower electrical resistivity, or a higher electroconductivity, than would be expected from...http://www.google.com.au/patents/US5545250?utm_source=gb-gplus-sharePatent US5545250 - Polytype electroconductive powders
