Hoʻohana mua ʻia ʻo Sintered Mullite a Fused Mullite no ka hana ʻana i nā refractory a me ka hoʻolei ʻana o ke kila a me nā huila Titanium.

Ua koho ʻia ʻo Sintered Mullite i ka bauxite kūlohelohe kiʻekiʻe, ma o ka homogenization multi-level, calcined ma luna o 1750 ℃. Hōʻike ʻia ia e ke kiʻekiʻe puʻupuʻu nui, kūpaʻa kūpaʻa kūpaʻa ʻana i ka haʻalulu haʻahaʻa haʻahaʻa, ka helu haʻahaʻa o ke kolo wela kiʻekiʻe a me ka maikaʻi o ka hoʻokō ʻana i ka corrosion a pēlā aku.

Kakaʻikahi loa i kona ʻano maoli, hana ʻia ka mullite no ka ʻoihana ma o ka hoʻoheheʻe ʻana a i ʻole ke puhi ʻana i nā alumini-silicates like ʻole. ʻO nā waiwai thermo-mechanical koʻikoʻi a me ka paʻa o ka mullite synthetic ka hopena e lilo ia i mea koʻikoʻi i nā noi refractory a me foundry.

ʻOiai ke ola nei ka mullite ma ke ʻano he mineral kūlohelohe, he mea kakaikahi loa nā hanana i ke ʻano.

Ke hilinaʻi nei ka ʻoihana i nā mullites synthetic i loaʻa ma ka hoʻoheheʻe ʻana a i ʻole ka 'calcining' ʻokoʻa alumino-silicates e like me kaolin, pālolo, kakaʻikahi a me ka silica maikaʻi a me ka alumina i nā wela kiʻekiʻe.

ʻO kekahi o nā kumu kūlohelohe maikaʻi loa o ka mullite ʻo kaolin (e like me nā pālolo kaolinic). He mea kūpono ia no ka hana ʻana i nā refractory e like me nā pōhaku i puhi ʻia a i ʻole i puhi ʻia, nā castables a me nā hui plastik.

Hoʻohana nui ʻia ka mullite sintered a me ka mullite fused no ka hana ʻana i nā refractory a me ka hoʻolei ʻana i nā mea kila a me nā titanium.
