Ultrafine copper powder - prices and manufacture
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 […]
