tabular alumina” refers to the raw material itself, “tabular refractory” refers to the finished product—a brick, castable, plastic, or other monolithic shape—that uses tabular alumina as its primary aggregate. What are Tabular Refractories? Tabular refractories are a class of high-alumina refractories where the main aggregate is tabular alumina. The goal is to transfer the superior properties of the
Platelet Calcined Alumina is a specialized form of aluminum oxide (Al₂O₃) characterized by its unique platelet-shaped morphology, which enhances mechanical, thermal, and wear-resistant properties in advanced ceramic and composite applications. Key Features: Platelet Morphology Hexagonal platelet-shaped particles improve fracture toughness by deflecting cracks (similar to natural nacre or layered composites). Enhances packing density in refractory and ceramic
Tabular Alumina is an advanced alumina product with superior thermal stability and excellent mechanical strength. It features high density, complete shrinkage, and low porosity, making it highly resistant to thermal shock and corrosion. This versatile product is suitable for use in the refractory, ceramics, and polishing industries. The Tabular Alumina offers excellent hardness and wear
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 Physical and Chemical Properties: Style(Item) chemical index physical index Al2O3(%) SiO2(%) Fe2O3(%) Na2O(%) Volume density (g/cm3) water absorption(%) apparent porosity(%) 0-1mm 1-3mm 3-5mm
Tabular Alumina is alumina obtained with the sintering of calcined alumina. The production of the own raw material basis, detailed control of process parameters and stable thermal processing ensure high-quality products in accordance with customer needs and requirements. During sintering, α-alumina crystals are combined to shape greater crystals, which give tabular alumina its specific properties.
tabular alumina is made of Al2O3, after ingredients, grinding and forming, smelting in high temperature furnace turned to α- Al2O3.. It 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
