JJ Techie calcined some ceramic powders at 1600℃ for 12 hrs, when removed from thefurnace, JJ was upset to find a big hard lump., After grinding up to the lump, someone told JJ to add a sintering aid and deflocculant to the ceramic before trying to press it into cylinders 10 inch by 0.25 inch in diameter. How could JJ do this well? JJ needs this size ceramic rod for experiments.

The following is a backscattered electron image of a sample of nickel alloy particles that were embedded in a resin, cut, and then polished to reveal the internal structure of the particles. From the image, explain whether you think the alloy has uniform composition or whether it is segregated into phases of different compositions. The resin used for embedding is an electrical insulator. How should such samples be treated before they are examined by SEM?
