ʻO ke kūpaʻa kiʻekiʻe a me ke kūpaʻa kiʻekiʻe-mahana:ʻO ke kūpaʻa ma luna o 1700 ℃, ka mahana palupalu o ka ukana >1600 ℃; paʻa i nā mahana kiʻekiʻe, kūpono no nā ʻāpana e halihali ana i ka ukana wela kiʻekiʻe (e like me nā uhi umu kila/umahana).
Kū'ē maika'i loa i ka palaho slag:ʻO ka Alkaline MgO a me ka inert Cr₂O₃ e hiki ai ke kūpaʻa ikaika i nā ʻōpala alkaline a me kekahi mau mea waikawa, ʻoi aku hoʻi i nā lewa oxidizing, e hoʻolōʻihi ana i ke ola o ka uhi o ka umu.
Paʻa maikaʻi o ka haʻalulu wela:Hoʻomaikaʻi ʻo Cr₂O₃ i ka hoʻonui ʻana o ka wela a me ka paʻakikī, e pale ana i ka nahā/pale ʻana i ka wā o nā loli wikiwiki o ka mahana (e like me ka hoʻomaka/pani ʻana o ka umu).
Ikaika kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu:Ikaika compressive/flexural kiʻekiʻe i ka mahana lumi; hōʻoia ka ʻili chromium oxide i ke kūpaʻa maikaʻi ʻana i ka hopena a me ka ʻaʻahu o ka mea umu.
Ke kūpaʻa ikaika i ka ʻinoʻino o ka metala/kinoea:Kūʻē i ka hao heheʻe, ke kila, a me nā kinoea umu (e laʻa me CO, CO₂) i nā mahana kiʻekiʻe, kūpono no nā ʻāpana i pili pono me nā metala heheʻe/nā kinoea mahana kiʻekiʻe.
Ka hoʻokele wela maikaʻi:Hoʻonui i ka hoʻoili wela a me ka pono wela o nā lako hana wela kiʻekiʻe.
Kū'ē maika'i loa i ka hō'ino'ino'ana o ka vacuum:Hana paʻa i ka hoʻoheheʻe ʻana i ka vacuum (e like me nā umu RH/DH/VOD), ʻaʻole i hōʻino maʻalahi.
