OUR

PRODUCT

TECHNOLOGY

Our patented solution is to produce polysilicon from decomposing silane gas in a centrifuge chamber. By utilizing a centrifuge reactor is it possible to avoid cooled surfaces within the reactor and increase the linear growth rate drastically to over 9 mm per hour and reduce the power consumption to below 3 kwh/kg in the decomposition reactor.

RESEARCH

The current reactor is the third generation of centrifuge reactors and the research has been performed in collaborating with Institute for Energy Technology in Norway. Combining state of the art modeling tools with extensive experimental research in industrially relevant scales is crucial in order to shape solutions that well perform well both today and in the years to come.

RECRUITMENT & COLLABORATION

Dynatec Engineering is constantly seeking new talents and specialists. Expanding our network of collaborative partners is important to us in order to continue to develop the technology that will shape the industry of tomorrow.

OUR VISION

We want to change the world and contribute to a greener tomorrow by enabling the industry with high quality low cost materials by the use of our centrifuge reactor technology.

We want to change the polysilicon industry by introducing a fundamentally new concept and move limits in combinations of quality and cost.

We want to move the limits of possible high quality material production at low cost by our centrifuge reactor technology. The possibilities in centrifuge chemical vapor deposition are vast and we want to explore them in collaboration with partners across the world.

THE CONCEPT

our_vision

In thermal decomposition the reactant or reactants are as a main rule heavier than the products. Whatever solid is deposited is part of the reactant and not the gaseous products. This means that if the chamber is rotating the heavy reactans will be forced to the wall by centripetal forces deposit the solid and the light product will be forced back to the center of the reactor and extracted.

By utilizing the centrifuge reactor the speed of the deposition process is greatly increased as both the reactant and the products are actively transported to and from the deposition surface. This reduces the need for cooling and the physical size of the chamber, which affect both the production, and capital cost of the process. The speed of the process also limits competing unwanted processes such as powder production.
