ABSTRACT:
A glaze resistor composition composed of magnesium silicide, molybdenum disilicide, tantalum disilicide and glass frit, and if necessary, manganese disilicide and/or aluminum oxide. Due to the use of magnesium silicide, glaze resistors having stable resistivities in a wide resistivity range can be obtained. Due to the use of manganese disilicide, the temperature coefficient of resistivity can be shifted to the positive side, and due to the use of aluminum oxide, the resistivity can be increased and made more stable. This invention also provides a method of making a glaze resistor using two heating steps, in which aluminum oxide is mixed in the starting powder mixture to be subjected to the first heating step, so as to enhance the effect of the aluminum oxide addition.
