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、�/span>

Description９�/span>

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�?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、�/span>

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, high 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９�/span>

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、�/span>

Application:

Tabular alumina is an ideal refractory material, either can be used in various refractory alumina, or can be add in other unshaped refractories
