Nhanganyaya yekuumbwa kwe fused mullite
Zvigadzirwa zvakasanganiswa mullite zvinowanzo shandisa yakakwira alumina bauxite, iron bauxite, maindasitiri alumina uye ivhu refractory semidziyo. Kusarudzwa kwakarurama kwezvigadzirwa zvakakosha maitiro ekugadzirisa zvidhinha zvakasanganiswa nepamusoro mullite content uye low corundum uye girazi zvikamu. Iyo aluminium oxygen coefficient yezvigadzirwa zvinomiririra hukama hweAl2O3 neSiO2 mune zvigadzirwa, uye nenzira isina kunanga inoratidza huwandu hwemullite inogadzirwa muchidhinha chakasanganiswa. Wedzera chiduku chiduku chekudzikisa (marasha kana coke yakanaka-grained) kune zvigadzirwa. Kuti uite gasi rinogadzirwa panguva yekunyunguduka nyore kupukunyuka, zviduku zvehuni zvehuni zvinofanira kuwedzerwa kune zvigadzirwa, uye kunyunguduka kunofanira kuitwa pakupisa kwe900-2200 ° C.
