Electrical Insulating Refractory Composition
US Patent:
4415674, Nov 15, 1983
Filed:
Apr 12, 1982
Appl. No.:
6/367198
Inventors:
Walter R. Johnson - Chuckey TN
Assignee:
Combustion Engineering, Inc. - Windsor CT
International Classification:
C04B 3504, C04B 3548
US Classification:
501104
Abstract:
Sheathed electrical heating elements containing MgO heat conductive, electrical insulating material having an additive of fine particles of spherically shaped fused ZrO. sub. 2 to increase the electrical resistivity and maintain favorable tap density and flow properties. The spherically shaped ZrO. sub. 2 particles are formed by gravitationally separating the ZrO. sub. 2 particles from ground fused zircon (ZrO. sub. 2. SiO. sub. 2).
