Large diamagnetism in pressure‐quenched CdS at 77 K or higher has been reported and the possibility of high‐temperature superconductivity was suggested to explain the near‐perfect flux exclusion. Among the various mechanisms invoked to predict high‐temperature superconductivity are exciton and plasmon exchange. Preliminary calculations of the superconducting transition temperature of CdS have been made using these mechanisms and the results will be reported.
