La(Fe,Si)13 is a kind of high-performance magnetic refrigeration materials, which has the advantages of simple preparation and environmental protection, as well as the disadvantages of poor mechanical properties and low thermal conductivity. The La(Fe,Si)13/Ag composite material was prepared by chemical deposit, in which the LaFeSi alloy powder was coated by Ag. Results show that thermal conductivity and density of composite materials are improved greatly. At the same time, the magnetic refrigeration capacity is kept well.
