Nitrogen nwere nnukwu elektrọnịkị ma nwee ike ịmepụta usoro nitrides nwere ọtụtụ ihe nwere obere elektrọnịkị, gụnyere ụdị nitrides ionic atọ, nitrides covalent na nitrides metal. Boron Nitride
Nitrides nke alkali metal na alkaline earth metal mejupụtara so na ionic nitrides, kristal ha bụkwa njikọ ionic, ihe nitrogen dịkwa n'ụdị N3-, nke a na-akpọkwa nitrides dị ka nnu. Njirimara kemịkalụ nke ionic nitrides na-arụ ọrụ karịa, a na-emekwa ka ha dị mfe iji mepụta hydroxides na ammonia kwekọrọ. Ugbu a, a na-eji Li3N na ionic nitrides. Li3N bụ ihe siri ike na-acha ọbara ọbara miri emi ma bụrụ nke sistemụ kristal hexagonal. Ọ nwere njupụta nke 1.27g/cm3 na ebe agbaze nke 813°C. Ọ dị mfe imepụta ma nwee nnukwu ionic conductivity. Enwere ike ijikọ ya na lithium siri ike ma ọ bụ mmiri mmiri. Ịdị n'otu bụ otu n'ime electrolytes lithium siri ike dị ugbu a.
Nitrides nke ihe otu IIIA~VIIA mepụtara bụ nitrides covalent, kristal ha na-achịkwa site na njikọ covalent. N'ime ha, a ga-akpọ ngwakọta ndị e ji oxygen, ihe otu VIIA na ihe nitrogen mepụta nke ọma nitrogen oxides na nitrogen halides. Nitrides covalent kachasị eji eme ihe bụ nitrides nke ihe IIIA na IVA (dịka BN, AlN, GaN, InN, C3N4 na Si3N4, wdg). Nkewa nhazi ahụ yiri tetrahedron nke diamond, ya mere a na-akpọkwa ya klaasị Diamond nitride. Ha nwere ike siri ike, ebe agbaze dị elu, na ezigbo nkwụsi ike kemịkalụ. Ọtụtụ n'ime ha bụ akụkụ ma ọ bụ semiconductor. A na-eji ha eme ihe nke ukwuu na ngwaọrụ ịkpụ, seramiiki okpomọkụ dị elu, ngwaọrụ microelectronic, na ihe ndị na-egbuke egbuke.
Nitrides nke ihe ndị mejupụtara ígwè mgbanwe na-apụta bụ nke nitrides ígwè. Atọm nitrogen dị na oghere lattice ígwè dị kubik ma ọ bụ hexagonal, nke a na-akpọkwa nitrides infill. Usoro kemịkalụ nke ụdị nitride a anaghị agbaso oke stoichiometric siri ike, ihe mejupụtara ya nwekwara ike ịdị iche n'ime oke. Ọtụtụ nitrides ụdị metal nwere nhazi ụdị NaCl, usoro kemịkalụ ahụ bụkwa ụdị MN.
