chemical catalyst na ihe dị mkpa akụrụngwa maka ime resistors na capacitors.

Isi na isi nke ịkwadebe ihe elektrọnik bụ tapawa eletrọnịkị, ogo ya na-emetụta arụmọrụ nke akụrụngwa ihe nkiri siri ike. Dị ka akụkụ dị mkpa nke tapawa eletrọnịkị, a na-akwado pasta resistor n'ime resistors eji na sekit ihe nkiri siri ike, nke a na-ejikarị na agha, ikuku ikuku, nkwukọrịta na mpaghara ụgbọ ala.
Ruthenium dioxide (RuO2) tapawa mgbochi bụ akụkụ dị mkpa nke tapawa mgbochi.

RuO2 nwere uru nke ọma catalytic ọrụ, ike chemical Njirimara, wdg, na bụkwa a metal-dị ka elu-conductivity metal oxide, nke ọtụtụ-eji na electrochemical catalysis, chlor-alkali ụlọ ọrụ na integrated sekit.
Ndị na-emegide nke RuO2 nwere uru nke oke nguzogide dị iche iche, ụda dị ala, ike nkwụsị ike siri ike, nkwụsi ike ibu dị elu, na ezigbo nkwụsi ike nchekwa ogologo oge.
Ya mere, Ru02 oké film resistor tapawa nwere nnukwu nha na mgbawa resistors na oké film integrated sekit.
