Njirimara ngwaahịa:
Isi ihe nke anụ ahụ na kemịkal: Ebe mgbaze nke zinc bụ 419.5 Celsius C, ebe a na-esi esi bụ 907 Celsius C, na njupụta na 0 Celsius C bụ 7.13g / cm3. Zinc na-agbaji n'oge okpomọkụ. Mgbe a na-ekpo ọkụ na 100 Celsius C ruo 150 Celsius C, enwere ike ịpịnye zinc n'ime efere dị nro ma ọ bụ dọba ya na wires ígwè, ma mgbe okpomọkụ gafere 250 Celsius C, ọ na-efunahụ ductility.
Zinc nwere ike meghachi omume na acid, bases na salts iji mepụta nnu ọhụrụ. Elu na-emekọrịta ihe na oxygen, carbon dioxide, na mmiri dị n'ikuku iji mepụta nnukwu zinc carbonate, nke na-echebe ngwaahịa ahụ ka ọ ghara ịdị na-ekpo ọkụ.
A machibidoro iji ngwa nkwakọ ngwaahịa na njem na acid, alkali, nnu na zinc ingots ndị ọzọ na-emebi emebi, na ekwesịrị ịchekwa ya n'ụlọ nkwakọba nkụ, ikuku ikuku, nke na-adịghị emebi emebi, ma chebe ya pụọ na mmiri ozuzo. Okpomọkụ na-agbaze nke zinc ekwesịghị gafere 500 ℃ iji belata mfu oxidation na mfu volatilite. O kwesịghị ịdị na kọntaktị na ígwè na ọla ndị ọzọ na-emerụ ahụ mgbe ọ na-agbaze ka ọ ghara imerụ ngwaahịa ahụ. A ga-emepụta zinc oxide n'elu ihe ngwọta zinc n'oge agbaze. Enwere ike iji ammonium chloride mee slag iji meziwanye ọnụego ojiji nke zinc. Ọ bụrụ na mmiri ozuzo ejirila zinc ingot ngwaahịa mmiri, ọ ga-akpọnwụ tupu ọ gbakwụnye mmiri a wụrụ awụ, ka ọ ghara "ịgbawa" imerụ ndị mmadụ ahụ ma mebie akụrụngwa.
