The present invention refers to a method for producing a component by joining individual wall parts—especially for producing a melting crucible for use at a high operating temperature in a crucible pulling method for quartz glass, in that at least two wall parts of a refractory metal or of a base alloy of a refractory metal are provided, butt-joined to form a joint and joined together by sintering at a temperature above 1500° C. to form the component. To provide a component of improved tightness and to ensure improved sintering of the individual parts of the component, a sealant is inserted into the joint. Furthermore, the present invention refers to a component produced according to the method, particularly a melting crucible, particularly in a crucible pulling method for quartz glass, in which the joint between the butt-joined walls is closed in a gas-tight manner by a sealant.
