HPA Sonics is focused on becoming one of the leading suppliers of 99.99% (4N) and 99.999% (5N) high purity alumina in North America
We have developed a unique and patented method for the production of high purity alumina and aluminum trihydrate that uses less energy and is more environmentally friendly than any other process that we are aware of. This process has been developed at our Wallingford, CT R&D facility and is now set to be commercialized in 2017.
High purity alumina serves as the base material for single crystal synthetic sapphire. The demand for this material, the second hardest substance on earth, is being driven by the growth in LED lighting (LED sapphire wafers hold 90% market share), the growth of the lithium ion battery market (where high purity alumina is used as a protective coating), and by the increasing use of protective sapphire glass for smartphones, smart watches and other wearable devices. Sapphire applications are also growing in the medical, defense and electronics industries.
In addition, aluminum trihydrate is among the world's leading fire retardants and has additional applications in plastics, paints, coatings, electronics, textiles, pharmaceuticals and other industries.
