Pure Alumina Limited has announced Polar Sapphire has received numerous orders for its top quality 5N high purity alumina (HPA).

Polar Sapphire is a Canadian company which is currently being acquired by Pure Alumina. Sales were received from a number of global sapphire producers who valued the high purity and physical properties with one customer sending a sapphire boulle grown for testing.

Testing done by EAG Laboratories shows an extremely high-purity (6N) of sapphire being achieved. This 6N sapphire will allow the customer to produce a higher yielding boule than 5N.

These orders were received from a number of global sapphire producers as the final stage for qualifying Polar’s product. Pure Alumina continues to get strong support in the sapphire market with products being used for LED’s, battery separators and optical lens manufacturers.

The continued demand and positive results from customers provides a high degree of confidence that the production of planned HPA will be very well received.
