Lanthanum target for sputtering
Abstract:
Provided are a lanthanum target for sputtering which has a Vickers hardness of 60 or more and no spotty macro patterns on the surface, and a method of producing a lanthanum target for sputtering, wherein lanthanum is melted and cast to produce an ingot, the ingot is subject to knead forging at a temperature of 300 to 500° C. and subsequently subject to upset forging at 300 to 500° C. to form the shape into a rough target shape, and this is additionally subject to machining to obtain a target. This invention aims to offer technology for efficiently and stably providing a lanthanum target for sputtering that has no spotty macro patterns on the surface, and a method of producing the same.
