Abstract

1,101,275. Sheathed resistance heating elements. KANTHAL A.B. 1 Nov., 1965, No. 46100/65. Heading H5H. One or more oxides of nickel, iron and copper are included in the insulation powder and/or are applied to the inner surface of the tubular sheath, and are stated to maintain the insulation resistance at a high value when the element has been at a high temperature (above 750‹ C. for a long time (100 hrs.) 1 to 2% by weight of nickel oxide or 1 to 3% of iron oxide may be added to magnesium oxide insulation powder. A layer from 10 to 100Á thick of iron, nickel or copper may be sprayed on to a heat-resistant strip and then oxidized in air or oxygen prior to forming the strip into a tube with the oxidized layer inside.
