Zirconium bụ ihe mejupụtara kemịkalụ nwere akara Zr yana akara atomịk nke 40. Ụdị mbụ ya bụ ọla agbaze dị elu ma na-egosi isi awọ. Zirconium na-adịkarị mfe ịmepụta ihe nkiri oxide n'elu ya, nke nwere ọdịdị na-egbuke egbuke dị ka ígwè. Ọ nwere nguzogide corrosion ma soluble na hydrofluoric acid na aqua regia. N'ebe okpomọkụ dị elu, ọ nwere ike imeghachi omume na ihe ndị na-abụghị ọla na ọtụtụ ihe ndị na-emepụta ihe na-emepụta ihe ngwọta siri ike.

Zirconium na-amịkọrọ hydrogen, nitrogen na oxygen ngwa ngwa; Zirconium nwere njikọ siri ike maka ikuku oxygen, oxygen gbazere na zirconium na 1000 Celsius nwere ike ịbawanye ụda ya nke ukwuu. Zirconium na-adịkarị mfe ịmepụta ihe nkiri oxide n'elu ya, nke nwere ọdịdị na-egbuke egbuke dị ka ígwè. Nwere nguzogide corrosion, mana ọ na-agbaze na hydrofluoric acid na aqua regia. N'ebe okpomọkụ dị elu, ọ nwere ike imeghachi omume na ihe ndị na-abụghị ọla na ọtụtụ ihe ndị na-emepụta ihe na-emepụta ihe ngwọta siri ike. Zirconium nwere ezigbo plasticity ma dị mfe ịhazi n'ime efere, wires, wdg Zirconium nwere ike ịmịnye nnukwu gas dị ka oxygen, hydrogen, na nitrogen mgbe ọ na-ekpo ọkụ, a pụkwara iji ya mee ihe dị ka ihe nchekwa hydrogen. Zirconium nwere nguzogide corrosion ka mma karịa titanium, na-abịaru nso niobium na tantalum. Zirconium na hafnium bụ ọla abụọ nwere akụrụngwa kemịkalụ yiri nke ahụ, na-ebikọ ọnụ ma nwee ihe ndị na-akpata redio.

Zirconium bụ ọla a na-adịghị ahụkebe nke nwere nguzogide corrosion dị ịtụnanya, ebe mgbaze dị oke elu, ike siri ike na ike dị elu, a na-ejikwa ya na mbara ikuku, agha, mmeghachi omume nuklia na mpaghara ike atọm. Ngwaahịa titanium na-eguzogide corrosion na nke siri ike nke ejiri na Shenzhou VI nwere nguzogide corrosion dị ala karịa zirconium, yana ebe mgbaze nke gburugburu ogo 1600. Zirconium nwere ebe mgbaze karịa ogo 1800, zirconia nwekwara ebe mgbaze karịa ogo 2700. Ya mere, zirconium, dị ka ihe aerospace, nwere arụmọrụ dị elu nke ukwuu n'akụkụ niile ma e jiri ya tụnyere titanium.
