ABSTRACT:
Semi-conducting materials which may be used in preparing resistors may be prepared by treating a refractory oxide with a pyrolyzable organic compound at an elevated temperature and thereafter further treating the resultant semi-conducting pyropolymeric inorganic refractory oxide composite material at an elevated temperature with subsequently controlled cooling rate to provide a material which possesses a lower resistivity and a controllable temperature coefficient of resistance over a wide range.
