US based GreenCell has announced that it has developed a new method for grinding ultrafine and ultrapure conductive powders.
The methods used earlier resulted in the production of a contaminant when the powders are ground at a nano scale. Under the new method, a clean ceramic ring grinder is used which has a density equivalent to lead. The company has completed the development and testing of the new technology. It will apply this technology to its sensors, fuel cell stacks and lighter line of products.
GreenCell has entered into a joint venture with SenCer for the commercialisation and marketing of UltraTemp ceramic composite materials from SenCer particularly used for transportation and home applications. Other industries where this new technology could be applied are oxygen sensors, ceramic heaters, SOFC fuel cells, braking and igniters.
