抄録

Lake Hamana situated near Mt. Fuji is a popular tourist spot attracting particularly an increasing number of marine sportspeople in recent years. With the active tourism and commercial development, however, the lake environment is burdened by accumulating sludge. In the present study, we attempted for recycling purposes to develop a new electronic material by mixing lake sludge with a Mn-Zn ferrite powder. The effects of mixing ratios and heat treatment conditions on the magnetic properties and microstructures of sintered samples were investigated. As a result, we found it possible to use such mixtures as composite materials for producing electromagnetic radiation absorbers with superior properties. Thus, we found that the magnetic characteristics of lake sludge mixed with a Mn-Zn ferrite powder are easily controllable. By optimizing various conditions, we should be able to apply lake sludge and ferrite powder mixtures to the manufacture of EMC and other magnetic devices.
