A na-akpọkwa brik na-emegharị ahụ dị ka arc brik. Blọkụ arc dị elu bụ ụdị brik nwere ụdị pụrụ iche. Aak nke blọk arc bụ ọkara okirikiri na nsọtụ ọzọ bụ uzo. , Enwere ike wulite ya na okirikiri, a na -eji ụdị brik a na ladle. A na -ejikarị brik arc eme ihe dị ka ime ime ịwụ nchara. Ọ na -abụkarị ụrọ. Ugbu a, a na -eji brik aluminom dị elu dochie ya. A na -amata brik dị elu alumina site na nguzogide ujo dị ọkụ, nguzogide corrosion siri ike na ike mkpakọ dị elu.
Bricks dị elu nke aluminom nwere brik aluminom nwere Al2O3 karịa 48% ruo 75%. Ihe dị elu nke ọdịnaya aluminom ka mma ka mma nke brik arc dị elu. Ọ bụ ihe na-adịghị anabata acidic, nke ejiri ihe okike ma ọ bụ ihe dị elu alumina mee (sillimanite, diaspore, alumina dị elu, wdg). E jiri ya tụnyere brik ụrọ, nrụgharị ya (1750 ~ 1790 ℃) na ibu ịdị nro dị arọ (1420 ~ 1500 ℃) dị elu, na nguzogide slag ya na ike mkpakọ ya dịkwa elu.
