Abstract
1459327 Resistor composition GLOBEUNION Inc 18 April 1974 [11 May 1973] 17064/74 Heading C1M A resistor composition comprises 1-10% by weight vanadium oxide and 1-30% by weight ruthenium dioxide, these oxides constituting an electrically conductive phase, and 50-98% by weight of a glass, the glass comprising 35- 45% by weight PbO, 15-25% by weight B 2 O 3 and 30-40% by weight SiO 2 , the balance of the glass, if any, consisting of other compatible constituents. The glass may also comprise 0-2% CaO and 0-2% Al 2 O 3 . The resistor composition optionally may also comprise, in the conductive phase, 1-15% by weight iridium dioxide, up to 10% by weight bismuth trioxide and/or up to 10% by weight Al 2 O 3 . The vanadium oxide is preferably V 2 O 5 , but V 2 O 3 may also be used. The resistor composition may be prepared from the resinates of Ru and Ir (if Ir is present) by: mixing the said resinates with the glass in frit form, vanadium oxide and (optional) Bi 2 O 3 and Al 2 O 3 ; heating to 300- 480 C. to remove organic material; calcining at 400-600 C. in air; reducing to a particle size of less than 20 Á; mixing with an organic vehicle (e.g. 2-ethyl-hexanol); screen-printing on to a ceramic insulating substrate (e.g. alumina); and firing at 850-950 C. Alternatively, the glass may be mixed directly with the appropriate oxides; mixed with 2-ethylhexanol; screen-printed on to the ceramic substrate; and fired at 850-950 C. The resistor produced exhibits a low temperature coefficient of resistivity.
