ʻO SnO2 kahi mea ʻike semiconductor koʻikoʻi me kahi ākea ākea, ʻo ia ka Eg = 3.6 eV ma ka wela lumi. No ka mea, loaʻa i nā nanomaterials nā hiʻohiʻona o ka liʻiliʻi liʻiliʻi a me ka nui kikoʻī kikoʻī, hiki ke hoʻomaikaʻi maikaʻi ʻia nā waiwai ʻike kinoea o nā mea. He kiʻekiʻe ka ʻike kinoea i hoʻomākaukau ʻia me ia a hoʻohana nui ʻia i ka ʻike ʻana a me ka wānana ʻana i nā kinoea combustible, nā kinoea hoʻohaumia kaiapuni, nā kinoea ʻona a me nā kinoea ʻino, e like me CO, H2S, NOx, H2, CH4, etc.
Ua hoʻomākaukau ʻia ka mea ʻike haʻahaʻa me SnO2 ma ke ʻano he kumu kumu i ka hoʻomaikaʻi ʻana i ke kaiapuni o loko, nā lumi mea hana pololei, nā hale waihona puke, nā hale kiʻi kiʻi, nā hale moʻomeheu a pēlā aku. Ma ka doping-quantitative Co0, Co2O3, Cr2O3, Nb2O5, Ta2O5, a me nā mea'ē aʻe ma SnO2, hiki ke hanaʻia nā varistors me nā koina kū'ē likeʻole, i hoʻohana nuiʻia i nā pūnaewele mana, nā kaapuni uila, a me nā mea hana hale.
