ABSTRACT:
A glassy resistor composition for use in a resistor incorporated spark plug is prepared by mixing 100 parts by weight of a mixture of 1-40% by weight of at least one of semiconductible oxides of metals selected from groups IVa and Va of the Periodic Table and a group of rare earth metals, 35-85% by weight of a glass powder and 5-35% by weight of a metal powder after a calcination, drying the resulting mixture, calcining the dried mixture and granulating the resulting mixture to form a base component, and compounding 100 parts by weight of the formed base component with 0.1-30 parts by weight of at least one of powdery carbides serving as reducing agents for the oxides and 0.1-20 parts by weight of inorganic or organic binder.
