Abstract

874,882. Thermistors. STANDARD TELEPHONES & CABLES Ltd. June 3, 1960 [June 5, 1959], No. 19313/59. Drawings to Specification. Class 37. A thermistor for use at high temperatures comprises a mixture of zirconia and 2-25% by weight of an oxide of yttrium, lanthanum cerium, praseodymium, neodymium, samarium europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, or lutetium and is formed by milling the oxides together, pressing them into suitable shapes, e.g. discs or rods and heating them to 1400‹ C. The faces of the discs or ends of the rods may be covered with platinum paste which is heated to 1300‹ C. to form platinum coatings.
