Umuvo wengqamuzana yeTuba (rutile), okuyintuhla ebalulekile yesinTsazayiya.INtuhla iwumxube wevanga enomcabayo oqukethe ngokungenaniiChwe elilodwalesOhwe kanye nenyeinhlwa. Intuhla ngokwayo iyisihonyo(ion) esinemilelesa ephikayo emibili yesOhwe. Imvama yegobohlalikaNomkhubulwane liqukethe izintuhla. Ngisho nezithako ezibhekwa njengezinhlwa ezicwebile nazo zivela uqweqwe lwentuhla. Ngokwesibonelo, incwazi yesAlumbe(aluminium foil) ivela isikhumba esilubunda se-Al2O3 (ebizwa ingqimba yentuhla) evikela incwazi ekugegedlekeni okuqhubekayo.
