Lub teeb yuag Mullite Insulating Bricks
Mullite bricks yog siab alumina refractories nrog mullite ua lub ntsiab siv lead ua theem. Feem ntau, cov ntsiab lus alumina nyob nruab nrab ntawm 65 feem pua thiab 75 feem pua , thiab cov refractory ntawm mullite cib yog qhov siab, nce siab tshaj 1790 degree.
