Reactive Alumina

   

Alumina is one of the most important oxide materials for technical ceramics and is used in a wide range of applications due to high mechanical strength and hardness, excellent resistance to both wear and chemical corrosion of the ceramic parts.

LISALTM alumina micropowders are low-sodium alumina powders with specified particle size distribution and thermal activity, which were produced using high-quality raw materials. They were calcined at a reasonable temperature in tunnel kiln and then ground with a specific grinding process.
LISALTM R series are high-purity sub-micron grade alumina designed for application that requires high density and low firing temperature. The unique sintering feature enables LISALTM R series to achieve high mechanical strength and homogeneous microstructure, making them ideal for electronics, advanced wear-resistant parts, semiconductors and other precious ceramics.
LISALTM C series are high-purity micron grade alumina designed for electronics, electronic substrates, and wear-resistant parts. They feature high conversion rate, strictly controlled particle size distribution, good fluidity, and thermal stability, allowing them to be processed in rolling, casting, dry pressing, isostatic pressing, hot die casting, and grouting.
LISALTM B series are low-soda bimodal alumina powders with excellent chemical resistance and dense particle packing. They can be used as filler, catalyst, technical ceramics and electronic ceramics.
LISAL TM B series are 99.9% submicron grade alumina powder with much lower content of Na2O and other impurities. It is specially designed for >99.5 alumina ceramics.
