Fused Alumina production is high energy-consuming. Each ton of fused alumina consumes 2000kWh to 3000kWh, while tabular alumina only consumes 20% to 35% of fused alumina. During production, fused alumina releases a large amount of waste gas and waste residue. Using natural gas as a heat producer, tabular alumina only generates carbon dioxide. After all, tabular alumina is superior to fused alumina both in energy saving and in environmental production.
Tabular alumina also has advantages over fused alumina in performance and index. First of all, tabular alumina has a low content of impurities and is evenly distributed. In the second place, since different parts of fused alumina have different cooling velocities, impurities in other parts vary accordingly. Thirdly, tabular alumina has a particular microscopic structure, and more ball-shape closed gas holes guarantee its good thermal shock resistance and anti-stripping performance.
In recent years, China’s domestic tabular alumina market has been developing at a fast pace both in aspects of quantity and qualification. As a result, the price of tabular alumina has decreased sharply. To some extent, using tabular alumina instead of fused alumina in refractory materials products can not only prolong products’ service life but also reduce consumption of refractory materials and energy.
Tabular alumina belongs to raw materials for high-end refractory material and will be used in broader application fields. Therefore, tabular alumina is making contributions to the entire refractory material industry.
