Ob leeg Fronkel thiab Schottky qhov tsis xws luag yog stoichiometric defects.
Qhov tsis xws luag yog stoichiometric defect?
Stoichiometric defects yog qhov tsis xws luag hauv qhov uas qhov piv ntawm cations rau anions tseem zoo ib yam li sawv cev los ntawm cov mis molecular. Lawv feem ntau yog ntawm ob hom: Ncua qhov tsis xws luag hauv uas ib qho atom tsis nyob ntawm nws qhov chaw lattice ua rau qhov chaw lattice tsis muaj thiab tsim qhov tsis xws luag.
Dab tsi yog ob hom stoichiometric defects?
- Muaj ob hom kev tsis xws luag stoichiometric. Ib tug yog scottky defect thiab lwm tus yog frenkel. Schottky qhov tsis xws luag tshwm sim thaum sib npaug ntawm cov cations thiab anions ploj ntawm lub lattice. -Frenkel qhov teeb meem tshwm sim thaum ib qho ion ploj lawm los ntawm nws qhov chaw lattice tiag tiag thiab nws nyob hauv ib qho chaw interstitial.
Puas yog Frenkel qhov tsis xws luag yog qhov tsis xws luag?
Ob leeg Frenkel thiab Schottky tsis xws luag yog stoichiometric defects.
Dab tsi yog qhov tsis xws luag stoichiometric thiab nonstoichiometric?
Stoichiometric vs Nonstoichiometric Defects
Stoichiometric defects yog cov uas tsis cuam tshuam cov stoichiometry ntawm ib qho compound. Nonstoichiometric defects yog qhov tsis xws ntawm cov qauv siv lead ua uas cuam tshuam cov stoichiometry ntawm cov siv lead ua. Qhov cuam tshuam rau Stoichiometry. Lawv tsis cuam tshuam rau stoichiometry ntawm cov compound.
