Pilikia Pālolo Pālolo Māmā

Hana ʻia nā pōhaku lepo ahi maʻemaʻe me nā mea palolo ahi ma lalo o ka wela kiʻekiʻe, ʻoi aku ka nui o ka nui, ikaika kiʻekiʻe, haʻahaʻa thermal conductivity a me ka haumia haʻahaʻa. ʻO ka mahana ma ka 1200-1400 ℃. Hoʻohui ʻia nā mea hoʻohui me ka wai i hana ʻia me ka mea plastik a i ʻole ka lepo, ka lepo me ka extrusion a i ʻole ka ninini ʻana i ke ʻano, 1250-1350 ℃ ma hope o ka ea wela wela. ʻO 0.75-1.2 g/cm3 ka mānoanoa o nā pōhaku lepo maʻamau. He ʻano refractory koʻikoʻi no ka mālama ʻana i ka ikehu a me ka mālama wela. Hiki ke hoʻohana ʻia nā pōhaku lepo lepo māmā i loko o nā kapuahi o ka hao a me ka hana kila, ka metala non-ferrous, nā mea hale, ka ʻoihana ikehu, etc.

Nā kiʻi:
1.Low pae o ka hao a me na mea haumia e ae,
2.High refractoriness,
3.High porosity, haʻahaʻa leo haʻahaʻa,
4.Good wela insulating hopena a me ka ikehu-efficient,
5.Good thermal haʻalulu paʻa,
6.Corrosion a me ka erosion kū'ē.
