Summary: In this study, a method for radial induction crystallization purification for the production of 6N, 7N seed crystals with ultra-high purity was presented. The influence of the cooling temperature on the morphology of the seed crystal as well as the cooling water temperature, the flow rate and the amount of seed added on the crystallization process were investigated, and the best cleaning process parameters were obtained as follows: temperature of the [...]
Like most nanomaterials, ultrafine copper powder is very expensive. In this article we describe where this high price comes from. This is not due to the cost of materials but rather to the complex production process. In order to obtain a copper powder that can be used for medical purposes, the particle size must not be larger than 1200nm (1,2µm), the […]
