Sumitomo to expand high purity alumina manufacturing facility


TOKYO, JAPAN: Sumitomo Chemical Co Ltd has decided to expand the production capacity of a manufacturing facility for high-purity alumina, used mainly as a raw material for sapphire substrates used in LEDs, from a current 1,600 tonne per year to 3,200 tonne per year.

In recent years, with the spread of LEDs used for backlights in personal computers and LCD televisions as well as in lighting applications, demand for high-purity alumina as a raw material for single-crystal sapphire used in LED substrates has been increasing.

Sumitomo is expanding its high-purity alumina business. In order to meet the increasing demand in recent years, the company embarked last year on a small-scale production capacity expansion from 1,600 tonne per year to 2,000 tonne per year. With demand expected to exceed projections, however, Sumitomo has reconsidered this plan and has recently decided to build a new production line that will bring its production capacity to 3,200 tonne per year. The new facility will be completed during the second quarter of 2012.

As the market for hybrid cars and electric vehicles expands, demand for high-purity alumina used in battery applications is expected to increase significantly. Seeing the potential, Sumitomo intends to study the possible construction in fiscal 2013 of another production line.
