摘要

A method for manufacture of crucibles, vessels, pipes and shaped products made of refractory materials with single crystal, polycrystalline and particular structure. The crucibles, tubes, pipes and shaped products made of refractory material are produced by layerwise facing using varieties of a highly concentrated energy source that allows to create a local area of molten material and at organization of its motion in the horizontal space, with injection of liquid metal, a layer of material is produced.
