Alpha HPA Ltd Information

Alpha HPA Ltd, formerly Collerina Cobalt Limited is advancing the the HPA First Process which is the application of the Company’s proprietary licenced solvent extraction and refining technology to produce HPA from an industrial feedstock. HPA is the pure form of aluminium oxide (Al2O3). HPA is the pre-cursor material for the manufacture of sapphire glass and ceramic coated Lithium-Ion-Battery (Li-B) separators. Its value derives from its physical properties of extreme hardness & chemical stability. Purity is determined by the concentration of trace elements in the alumina compound e.g, iron, magnesium, sodium. Price and performance of HPA varies upon product density, crystal structure, particle size and distribution and degree of purity.
