    Abstract: A unibody, monolithic, one-piece negative draft crucible (40) for an MBE effusion source (110). The crucible (40) maximizes capacity, uniformity and long-term flux stability, and minimizes oval defects, depletion effects, and short-term shutter-related flux transients. The invention also includes an effusion source (110) employing such a crucible (40), as well as a method and mandrel apparatus (55) for making a unibody containment structure (40), such as a crucible (40) formed of PBN, having a negative draft (46), via chemical vapor deposition.

    Abstract: A crucible capable of withstanding high temperatures and receiving materials to be melted, decomposed or generally converted while avoiding any physical or chemical interaction between the material making up the crucible and its contents. The crucible is made of a refractory material and designed to contain high temperature materials, and its inner wall comprises a coating based on a thin layer with a thickness below 10 mu m. The layer is preferably oxide-based and at least the inner wall of the crucible is advantageously made of vitreous silica.

    Abstract: The method provides melting granules of precious metal contained in a graphite ingot mold (2), in a sealed melting chamber (20), by induction heating means (21) and with an inert gas atmosphere instead of air. The solidification of the ingot is carried out by placing the ingot mold (2) on a cooling plate (3) in which a coolant circulates. The cooling plate (3) is situated in a loading/cooling chamber (10) provided to couple and decouple with the melting chamber (20); the solidification phase of the ingot is also carried out while keeping the loading/cooling chamber (10) closed. The device (1) which carries out the method has a box structure (4) to which is cantilevered the melting chamber (20) and to which is pivotably jointed at least one loading/cooling chamber (10). The latter is movable between said coupled and decoupled positions and can be arranged at the side of the melting chamber (20). With the proposed method and device it is prevented the oxidation of the ingot mold (2) and their rapid wear.
