   四成板狀剛玉，是進口氧化鋁經(jīng)配料、粉磨和成型后，在略低于其熔點的超高溫條件下燒結完全的再結晶α- Al2O3。

     Description：

     Sicheng tabular alumina is made of Al2O3, after ingredients, grinding and forming, smelting in high temperature furnace turned to α- Al2O3.

     產品特性：

     板狀剛玉具有良好的加熱體積溫度性和良好的抗熱震能力。其晶體呈平板狀交錯排列，增加了顆粒的機械強度;晶內和晶間以分布均勻的閉氣孔為主，體積密度高，顯氣孔和吸水率低，減少了再制品的用液量;具有高耐火度、良好的熱震穩(wěn)定性、低熱收縮率和良好的熱負荷強度等優(yōu)越的物理性能。同時，高純度避免了雜質對系統(tǒng)的污染，是制作高級耐火材料、陶瓷材料和絕緣材料的理想原料。

     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, 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. Sicheng is your best choose as refractory material/ceramic material and insulating materials.

     應用：

     板狀剛玉是一種理想的耐火材料，既可以作為骨料應用于各種鋁質耐火材料中，也可以添加到其他鋁質不定型耐火材料中。

    Application:

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