Inona ny akora ilaina biriky marefo?

Misy karazany maro ny akora hanaovana biriky refractory. Avy amin’ny fomba fijery simika, ny singa rehetra sy ny fitambarana misy teboka avo lenta dia azo ampiasaina ho akora fototra; Avy amin’ny fomba fijery mineralogy, ny mineraly avo lenta rehetra dia azo ampiasaina ho toy ny akora ho an’ny biriky refractory. Inona avy ireo akora ny refractory biriky, amin`ny ankapobeny mizara ho: tany, vato, fasika, silty sy ny hafa.

(1) Toetran’ny tany: kaolin, tanimanga ary diatomita

(2) kalitao vato: bauxite, fluorite, kyanite, andalusite, sillimanite, forsterite, vermiculite, mullite, chlorite, dolomita, magnesia alumina spinel sy silica, Cordierite, corundum, coke vatosoa, zircon

(3) Fasika kalitao: fasika quartz, fasika magnesia, chrome ore, sns.

(4) kalitaon’ny vovoka: vovoka aluminium, vovoka silisiôma, vovoka silisiôma

(5) hafa: asfalta, graphite, phenolic resin, perlite, vakana mitsingevana, vera rano, silica sol, simenitra aluminate kalsioma, shale ceramsite, aluminium sol, silisiôma carbide, hollow sphere
