Ihe ngosi teknụzụ a na-ahụkarị nke brik sphere oghere alumina bụ: ọdịnaya Al2O3 abụghị ihe na-erughị 98%, ọdịnaya SiO2 abụghị karịa 0.5%, ọdịnaya Fe2O3 abụghị karịa 0.2%, njupụta buru ibu bụ 1.3 ~ 1.4g / cm3, porosity pụtara ìhè. bụ 60% ~ 80%, The mkpakọ ike bụ bụghị ihe na-erughị 9.8MPa, nro okpomọkụ nke ibu (0.2MPa) bụghị ihe na-erughị 1700 ℃, na thermal conductivity bụ 0.7 ~ 0.8W / (m · K).
E jiri ya tụnyere ihe mkpuchi ọkụ nkịtị na ngwaahịa refractory, alumina oghere oghere a na-eji ọnụ ọgụgụ dị ukwuu nke pores mechiri emechi na ngwaahịa ahụ. Ya mere, ọ nwere nnukwu ike na kwụsiri ike pore Ọdịdị, ala njupụta na ala thermal conductivity. A na-ejikarị ya eme ihe maka okpomọkụ dị elu n'okpuru 1800 ℃ Industrial kiln lining, dị ka brik dị elu na-ekpo ọkụ na refractory, ngwá electronic, na seramiiki ụlọ ọrụ; Okpokoro mkpuchi ọkụ maka akụrụngwa okpomọkụ dị elu, dị ka ọkụ gas na ụlọ ọrụ petrochemical, ọkụ gas, igwe nrụpụta coal, brik mkpuchi maka ọkụ induction na ụlọ ọrụ ọla.
B zirconia oghere oghere brik
Zirconia oghere oghere brik bụ ngwaahịa na-ekpo ọkụ na-ekpo ọkụ nke ejiri oghere zirconia mee dị ka ihe bụ isi akụrụngwa. Akụkụ kristal bụ isi nke brik a bụ cubic zirconia (ihe dị ka 70% ruo 80% nke ihe mejupụtara mineral), yana arụmọrụ ya bụ: Refractoriness karịrị 2400 ℃, porosity pụtara ìhè bụ 55% ~ 60%, njupụta olu. bụ 2.5 ~ 3.0g / cm3, ike mkpakọ abụghị ihe na-erughị 4.9MPa, na conductivity thermal bụ 0.23 ~ 0.35W / (m·K).
Ebe oghere Zirconia bụ ngwaahịa na-ekpo ọkụ na-ekpo ọkụ na-arụ ọrụ nke ọma. Okpomọkụ kachasị mma maka ojiji bụ 2200 ℃. Zirconia oghere sphere brik nwere dịtụ elu-okpomọkụ ike na kwụsiri ike pore Ọdịdị, n'ihi ya, ha nwere ike na-eji n'enweghị na a elu okpomọkụ nke 2200 ℃. Zirconia oghere bọl brik nwere obere njupụta na obere okpomọkụ conductivity, nke nwere ike ọ bụghị nanị ibelata okpomọkụ ọnwụ, ma na-ebelata okpomọkụ nchekwa. Ya mere, dị ka ihe mkpuchi okpomọkụ dị elu nke na-akpọtụrụ ọkụ na ngwá ọrụ okpomọkụ dị ka metallurgy, petroleum, chemical ụlọ ọrụ, ngwá electronic, wdg, ọ nwere ike ibelata oriri ume ma belata ibu nke ọkụ ọkụ ọkụ ọkụ, na iji ya mee ihe. mmetụta dị mma.
