Abstract: This invention relates to reusable crucibles for production of ingots of semiconductor grade silicon made of nitride bonded silicon nitride (NBSN). The crucibles may be made by mixing silicon nitride powder with silicon powder, forming a green body of the crucible, and then heating the green body in an atmosphere containing nitrogen such that the silicon powder is nitrided forming the NBSN-crucible. The crucibles may be assembled by plate elements of NBSN-material that are to be the bottom (1) and walls (3, 5) of a square cross-section crucible, and optionally sealing the joints by applying a paste comprising silicon powder and optionally silicon nitride particles, followed by a second heat treatment in a nitrogen atmosphere.

Abstract: The application relates to a method and means for electrolytic production of metals or alloys in chloride melts. The problem to be solved is to find an anode material that can replace carbon/ graphite, particularly in electrolytic processes with CaCl2-CaO based electrolytes, such as the FFC process and the OS process. As a solution to this problem, the application presents a number of possible candidate materials, based on at least one of NiO, CaTiO3, CaZrO3, CaSnO3 or Ca2Fe2O5.
