In order to produce their nano powders, Tekna has to buy expensive high purity silicon.
HPQ starts with cheap low purity quartz, reduce it into silicon using Purevap QRR, and then transforms it's silicon into nano powders, using Purevap NSiR.
They are no competition to HPQ, the market will buy it's silicon nano powders from the company that can afford to sell it's product at the lowest price.
