ʻO nā pōhaku lepo ʻo Sillimanite kahi ʻano o nā pōhaku refractory kiʻekiʻe me ka refractoriness kiʻekiʻe o 1770 ~ 1830 ℃ a me ka refractoriness kiʻekiʻe ma lalo o ke kaumaha o 1500 ~ 1650 ℃, nona ka waiwai kino a me ke kemika i ʻoi aku ka maikaʻi ma mua o nā pōhaku alumina kiʻekiʻe. Hoʻololi ʻia ʻo Sillimanite i mullite a me ka manuahi silicon dioxide ma hope o ke puhi ʻana i ka wela kiʻekiʻe. Hoʻohana maʻamau ʻo Sillimanite refractory i ke kaʻina hana o ke ahi wela kiʻekiʻe a me ke kaʻina ninini lepo.
ʻO nā pōhaku ahi ʻo Sillimanite no ka refractory neutral. Hana ʻia ʻo Sillimanite brick i nā minerale sillimante, hiki ke hoʻololi i ka mullite a me ka silica manuahi ma hope o ka puhi ʻana i ka wela kiʻekiʻe. Hana ʻia nā brick refractory sillimanite e nā ʻano o ke kī ʻana a me ka hoʻolei ʻana.
Hana ʻia nā pōhaku lepo Sillimanite me nā mea waiwai nui o ka sillimanite, ʻo ka sillimanite kahi ʻano o ka refractory maka waiwai a hoʻohana ʻia e hana i nā pōhaku alumina kiʻekiʻe me ka haʻahaʻa creep, refractoriness kiʻekiʻe ma lalo o ka ukana, ka haʻalulu wela kiʻekiʻe a me ka micro-expansive, a me ka umu wela. Hiki ke hoʻololi ʻia ka sillimanite i mullite a me ka silicon dioxide manuahi ma o ka puhi wela kiʻekiʻe. ʻOi aku ka maikaʻi o ka waiwai kino a me ka waiwai kemika sillimanite ma mua o nā pōhaku alumina kiʻekiʻe. ʻO ka refractoriness brick ahi ʻo Sillimanite he 1770 ~ 1830 ℃ a ʻike ʻia ka mahana palupalu mua o 1500 ~ 1650 ℃.
