简介: 烧结板状刚玉,是进口氧化铝经配料、粉磨和成型后,在略低于其熔点的温条件下烧结完全的再结晶α- Al2O3。 Description: Haixu/Sicheng tabular alumina is made of Al2O3, after ingredients, grinding and forming, smelting in high temperature furnace turned to α- Al2O3. 产品特性: 烧结板状刚玉0-1-3-5-8mm具有良好的加热体积温度性和良好的抗热震能力。其晶体呈平板状交错排列,增加了颗粒的机械强度;晶内和晶间以分布均匀的闭气孔为主,体积密度高,显气孔和吸水率低,减少了再制品的用液量;具有高耐火度、良好的热震稳定性、低热收缩率和良好的热负荷强度等的物理性能。同时,高纯度避免了杂质对系统的污染,是制作耐火材料、陶瓷材料和绝缘材料的理想原料。 Production feature: Tabular alumina has good heat resistance and good bulk temperature thermal shock capabilities. The crystal staggered plate shape, to increasing the mechanical strength of the particles; interior structure full of closed pores, bulk density, low apparent porosity and water absorption, to reducing the amount of fluid re-use productions; With good physical properties like: high refractoriness, excellent thermal shock resistance, low shrinkage and good thermal load strength etc. Meanwhile, high-purity avoiding damage to machines. Hiaxu/Sicheng is your best choose as refractory material/ceramic material and insulating materials. 应用: 板状刚玉是一种理想的耐火材料,既可以作为骨料应用于各种铝质耐火材料中,也可以添加到其他铝质不定型耐火材料中。 Application: Tabular alumina is an ideal refractory material, either can be used in various refractory alumina, or can be add in other unshaped refractories Used for refractory 型号 Style 化学成分chemical index 物理指标 physical index Al2O3% SiO2% Fe2O3% Na2O % 体积密度 Volume density (g/cm3) 吸水率 water absorption 显气孔率 apparent porosity 0-1mm 1-3mm 3-5mm 5-8mm 99.3 min 0.1 max 0.02 max 0.4 max 3.5 1.5 5max 200#-0 320#-0 325# 99.1 min 0.15 max 0.04 max 0.4 max 3.45 2.0 6max
