A nickel, chromium, cobalt, iron, molybdenum, manganese, aluminum, titanium, niobium, silicon welding alloy, articles made therefrom for use in producing weldments and methods for producing these weldments. The cost effective synergistic composition is useful for the preparation of improved silicon carbide powder containing at least 90% SiC preferably rich in the \u03b2-phase. During the probing mode, the server pushes useful data to the application for the latter to perform the estimation. Another base 11 is coated with a third polymer electrolytic solution 12 to form a second polymer electrolytic membrane 12b which is undried. The S-CSCF then stores the AoC indicator for the IMS user.
