Abstract

Experimental evidence of superconductors with critical temperatures above 373K373\:K is presented. In a family of different compounds we demonstrate the superconductor state, the transition to normal state above 387K387\:K, an intermediate 242K242\:K superconductor, susceptibility up to 350K350\:K, IVI-V curves at 4.2K4.2\:K in magnetic field of 12T12\:T and current up to 60A60\:A, 300K300\:K Josephson Junctions and Shapiro steps with radiation of 5GHz5\:GHz to 21THz21\:THz, 300K300\:K tapes tests with high currents up to 3000A3000\:A and many THzTHz images of coins and washers. Due to a pending patent, the exact chemical characterization and technological processes for these materials are temporarily withheld and will be presented elsewhere.
