Milling effect on the flow ability of a superconductor powder
Principle. Since the discovery of high temperature superconductors (HTS) by Bednorz and Müller in 1986, considerable research effort has been devoted to the study and improvement of the superconducting properties of such materials...
To guarantee a high reproducibility of processes, a lot of applications need the use of free flowing powders. For plasma spraying deposition, for example, the substrate needs to receive a regular and constant flow mass of powder during all the projection duration...
Limestone (Calcium carbonate) powders and the derivative products are extensively used in the construction industry, in chemical and metallurgical industries and also in agriculture.
