Zirconium: ʻO Zirconium kahi mea kemika nona ka hōʻailona kemika ʻo Zr. ʻO kona helu ʻātoma he 40. He metala keʻokeʻo keʻokeʻo kiʻekiʻe me ke kala hina hina. ʻO ka mānoanoa he 6.49 g / cm 3. ʻO ka helu hoʻoheheʻe he 1852 ± 2 ° C, ʻo ka paila paila he 4377 ° C. ʻO ka valence he +2, +3 a me +4. ʻO ka ikehu ionization mua he 6.84 eV. He mea maʻalahi ka ʻili o ka zirconium e hana i kahi kiʻiʻoniʻoni oxide me kahi luster, no laila ua like ke ʻano me ke kila. He pale ʻino a hiki ke hoʻoheheʻe ʻia i ka waika hydrofluoric a me ka aqua regia. Hoʻopili ia me nā mea metala ʻole a me nā mea metala he nui i nā wela kiʻekiʻe e hana i nā pūhui hoʻonā paʻa. nā noi o ka zirconium: ka waiwai o ka ikehu nuklea, ke kū ʻana o ka corrosion maikaʻi loa, ka helu hoʻoheheʻe kiʻekiʻe, ka ikaika kiʻekiʻe a me ka paʻakikī, ka hana super i nā haʻahaʻa haʻahaʻa.
