Molybdenum and molybdenum alloy products, such as molybdenum plate, molybdenum rod, molybdenum wire, molybdenum tube, molybdenum foil, etc., are prepared by powder metallurgy and subsequent deformation processing technology. The mixed molybdenum and molybdenum alloy powders are first made into green compacts by conventional pressing or isostatic pressing techniques. The compacts are then sintered in a
