The need to reduce metal content, especially Palladium content in the multi layer ceramic components is driven by two motives. The first is the need to reduce material costs which has become a major i...
A New Method for the Preparation of Fine-Grained SnO2 and WO3 Powders: Influence of the Crystallite Size on the Electrochemical Insertion of Li+ in SnO2 and WO3 Electrodes
Fine-Grained SnO2 and WO3 Powders the Electrochemical Li+ SnO2 and WO3 Electrodes
2010/12/14
We propose an unconventional method to obtain fine-grained SnO2 and WO3 powders. It uses as precursors, polymer complexes between polyethylene oxide (POE) and SnCl4 or WCl6 respectively. By pyrolysis ...
