Naetrojene e na le electronegativity e phahameng mme e ka theha letoto la nitrides tse nang le dielemente tse ngata tse nang le electronegativity e tlase, ho kenyeletswa le mefuta e meraro ya ionic nitrides, covalent nitrides le metal nitrides. Boron Nitride
Li-nitride tse entsoeng ke litšepe tsa alkali le likarolo tsa tšepe tsa alkaline earth ke tsa li-nitride tsa ionic, 'me likristale tsa tsona haholo-holo ke litlamo tsa ionic, 'me likarolo tsa naetrojene li teng ka sebopeho sa N3-, e boetse e bitsoa li-nitride tse kang letsoai. Litšobotsi tsa lik'hemik'hale tsa li-nitride tsa ionic li sebetsa haholoanyane, 'me li haelloa habonolo ho hlahisa li-hydroxide le ammonia tse tsamaellanang. Hona joale, Li3N ho li-nitride tsa ionic ea sebelisoa. Li3N ke solid e khubelu e tebileng 'me ke ea sistimi ea kristale ea hexagonal. E na le boima ba 1.27g/cm3 le ntlha ea ho qhibiliha ea 813°C. Ho bonolo ho e kopanya 'me e na le conductivity e phahameng ea ionic. E ka kopanngoa le lithium e tiileng kapa e metsi. Ho ba teng hammoho ke e 'ngoe ea li-electrolyte tsa lithium tse tiileng tse fumanehang hona joale.
Li-nitride tse entsoeng ke likarolo tsa sehlopha sa IIIA~VIIA ke li-nitride tsa covalent, 'me likristale tsa tsona li laoloa ke litlamo tsa covalent. Har'a tsona, metsoako e entsoeng ke oksijene, likarolo tsa sehlopha sa VIIA le likarolo tsa naetrojene li lokela ho bitsoa li-oxide tsa naetrojene ka nepo le li-halide tsa naetrojene. Li-nitride tsa covalent tse sebelisoang haholo ke li-nitride tsa likarolo tsa IIIA le IVA (tse kang BN, AlN, GaN, InN, C3N4 le Si3N4, jj.). Yuniti ea sebopeho e tšoana le tetrahedron ea daemane, kahoo e boetse e bitsoa nitride ea sehlopha sa Diamond. Li na le bothata bo phahameng, ntlha e phahameng ea ho qhibiliha, le botsitso bo botle ba lik'hemik'hale. Bongata ba tsona ke 'mele ea bohale kapa li-semiconductor. Li sebelisoa haholo lisebelisoa tsa ho seha, li-ceramics tsa mocheso o phahameng, lisebelisoa tsa microelectronic, le thepa ea khanya.
Li-nitride tse entsoeng ke likarolo tsa tšepe tse fetohang ke tsa li-nitride tsa tšepe. Liathomo tsa naetrojene li fumaneha ka har'a likheo tsa tšepe tse nang le li-cubic kapa tse nang le mahlakore a tšeletseng, tse boetse li bitsoa li-nitride tse tlatsang. Foromo ea lik'hemik'hale ea mofuta ona oa nitride ha e latele karolelano e tiileng ea stoichiometric, 'me sebopeho sa eona se ka fapana ka har'a mefuta e fapaneng. Li-nitride tse ngata tsa mofuta oa tšepe li na le sebopeho sa mofuta oa NaCl, 'me foromo ea lik'hemik'hale ke mofuta oa MN. Ka kakaretso, e na le thepa e kang ea tšepe, joalo ka khanya ea tšepe, conductivity e ntle, thatafalo e phahameng, ntlha e phahameng ea ho qhibiliha, tšenyo le ho hanyetsa mafome, jj., 'me e na le menyetla e metle ea ts'ebeliso ho thepa ea ho seha, thepa ea motlakase le thepa ea catalytic.
