ʻO ka zircon firebrick e pili ana i ka brick refractory i loaʻa nā mea maka o zircon a i ʻole ZrO2 ma mua o 90%. Ma waho aʻe o kēia, aia kekahi mau brick refractory i loaʻa i ka zircon, e like me ka Zr-Al brick, hiki i ka zirconia firebrick ke hoʻomaikaʻi i ke kūpaʻa haʻalulu wela; Zr-Cr-Al brick, kahi e hoʻomaikaʻi ai i ka refractoriness a me ka pale anti-corrosion; a me Zr-SiC brick e hoʻomaikaʻi i ka slag a me ke kūpaʻa ʻana. zirconia brick nā waiwai like ʻole o ka ikaika mechanical kiʻekiʻe, ke kūpaʻa haʻalulu wela maikaʻi, ka refractoriness kiʻekiʻe ma lalo o ka ukana, ke kūpaʻa erosion ikaika a me ke kiʻekiʻe kiʻekiʻe.
Hana ʻia ka pā ahi zircon mai ke one zircon paʻa kahi ʻano o ka pōhaku refractory nui me ka ʻike zircon ma luna o 64%. ʻO ka zircon refractory block he acid refractory me nā mea maikaʻi o ka ikaika mechanical kiʻekiʻe, ka refractoriness kiʻekiʻe ma lalo o ka ukana, ke kūpaʻa haʻalulu maikaʻi maikaʻi, ke kūpaʻa creep maikaʻi a me ke kūpaʻa corrosion maikaʻi i ka wai aniani.

Hiki ke hoʻohana nui ʻia nā pōhaku lepo Zircon i ka umu aniani, Ladle, ka umu kila maʻemaʻe, ka umu hoʻoheheʻe ʻole ferrous, a me nā pōhaku ahi zirconia i kūpono no ka kiln aniani, hoʻolei ʻia nozzle o ka umu hoʻoheheʻe nonferrous, a me ka ladle lining, etc.
