ʻO Zirconium kahi mea kemika me ka hōʻailona Zr a me ka helu atomika o 40. ʻO kona ʻano kumu he metala hoʻoheheʻe kiʻekiʻe a ʻike ʻia ka hina hina. Hiki i ka Zirconium ke hana i kahi kiʻiʻoniʻoni oxide ma luna o kona ʻili, nona ke ʻano nani e like me ke kila. Loaʻa i ka corrosion a hiki ke hoʻoheheʻe ʻia i ka waika hydrofluoric a me ka aqua regia. I nā wela kiʻekiʻe, hiki iā ia ke hana me nā mea metala ʻole a me nā mea metala he nui e hana i nā haʻina paʻa.

Hoʻopili maʻalahi ʻo Zirconium i ka hydrogen, nitrogen, a me ka oxygen; He ikaika ko Zirconium no ka oxygen, a me ka oxygen i hoʻoheheʻe ʻia i ka zirconium ma 1000 ° C hiki ke hoʻonui nui i kona leo. Hiki i ka Zirconium ke hana i kahi kiʻiʻoniʻoni oxide ma luna o kona ʻili, nona ke ʻano nani e like me ke kila. Loaʻa i ka corrosion, akā hiki ke hoʻoheheʻe ʻia i ka waika hydrofluoric a me ka aqua regia. I nā wela kiʻekiʻe, hiki iā ia ke hana me nā mea metala ʻole a me nā mea metala he nui e hana i nā haʻina paʻa. ʻO Zirconium ka maikaʻi o ka plasticity a he maʻalahi ke hana i loko o nā papa, nā uea, a me nā mea'ē aʻe. Hiki i ka Zirconium ke komo i ka nui o nā kinoea e like me ka oxygen, hydrogen, a me ka nitrogen ke hoʻomehanaʻia, a hiki ke hoʻohanaʻia ma keʻano he mea mālama hydrogen. ʻOi aku ka maikaʻi o ka pale ʻana o ka zirconium ma mua o ka titanium, e hoʻokokoke ana i ka niobium a me ka tantalum. ʻO Zirconium a me ka hafnium nā metala ʻelua me nā waiwai kemika like, e noho pū ana me nā mea radioactive.

ʻO Zirconium kahi metala kakaʻikahi me ke kūpaʻa corrosion kupaianaha, ka helu heheʻe kiʻekiʻe, ka paʻakikī kiʻekiʻe kiʻekiʻe a me ka ikaika, a hoʻohana nui ʻia i ka aerospace, ka pūʻali koa, nā hopena nuklea, a me nā māla atomika. ʻO nā huahana titanium kūpaʻa a kūpaʻa loa i hoʻohana ʻia ma Shenzhou VI he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ma mua o ka zirconium, me kahi helu heheʻe ma kahi o 1600 degere. He wahi hehee ko Zirconium ma luna o 1800 degere, a he wahi hehee ko zirconia ma luna o 2700 degere. No laila, ʻo ka zirconium, ma ke ʻano he aerospace, ʻoi aku ka maikaʻi o ka hana ma nā ʻano āpau i hoʻohālikelike ʻia me ka titanium.
