Modern high‐performance ceramics , such as silicon nitride, silicon carbide, and aluminum nitride are manufactured from ceramic powders (see figure) which have to meet sstringent requirements regarding purity and grain size. Control of the grain size during the first steps of the chemical synthesis of the powders is importnat and has been achieved in the manufacture of silicon nitride via silicon diimide, and aluminum nitride via the carbothermal nitridation of aluminum hydroxide.
