Imicu ye-ceramic eyi-refractory iwuhlobo lwempahla engajwayelekile enezimbotshana enesakhiwo esincane esiyinkimbinkimbi. Ukunqwabelana kwemicu akwenzeki futhi akuhlelekile, futhi lesi sakhiwo sejiyomethri esingajwayelekile siholela ezinhlobonhlobo zezakhiwo zazo ezibonakalayo.
I-Fiber density
Imicu ye-ceramic refractory ekhiqizwa indlela yokuncibilika kwengilazi, ukuminyana kwemicu kungathathwa njengokufana nokuminyana kwangempela. Uma izinga lokushisa ngezigaba lingu-1260 ℃, ukuminyana kwemicu ephikisayo kungu-2.5-2.6g/cm3, futhi lapho izinga lokushisa ngezigaba lingu-1400 ℃, ukuminyana kwemicu ye-ceramic eyi-refractory ngu-2.8g/cm3. Imicu ye-polycrystalline eyenziwe nge-aluminium oxide inobuningi beqiniso obuhlukile ngenxa yokuba khona kwama-micro pores phakathi kwezinhlayiya ze-microcrystalline ngaphakathi kwemicu.
Ububanzi befiber
I-fiber diameter yeimicu ye-ceramic refractoryekhiqizwa indlela yokubumba yomjovo wezinga lokushisa eliphezulu isukela ku-2.5 kuya ku-3.5 μ m. Ububanzi be-fiber yezintambo ze-ceramic eziphikisayo ezikhiqizwa indlela yokuphotha esheshayo yezinga eliphezulu lokushisa ngu-3-5 μ m. Ububanzi bemicu ye-refractory abuhlali ngaphakathi kwalolu hlu, futhi imicu eminingi iphakathi kuka-1-8 μm. Ububanzi bemicu ye-ceramic ye-refractory buthinta ngokuqondile amandla kanye nokusebenza okushisayo kwemikhiqizo ye-fiber refractory. Uma i-diameter ye-fiber inkulu uma kuqhathaniswa, imikhiqizo ye-fiber refractory izwa kanzima uma ithinta, kodwa ukwanda kwamandla nakho kwandisa ukuguquguquka kwe-thermal. Emikhiqizweni ye-fiber refractory, ukuqhutshwa kwe-thermal namandla emicu ngokuyisisekelo kuhambisana ngokuphambene. Isilinganiso sobubanzi be-alumina polycrystalline ngokuvamile singu-3 μ m. Ububanzi bemicu eminingi ye-ceramic ephikisayo buphakathi kuka-1-8 μ.
