The invention provides a ceramic body and a method of manufacturing such a body. The body is characterized by its composition, which comprises 20-30 at. % of magnesium, 20-30 at. % of silicon, 40-60 at. % of nitrogen and maximally 15 at. % of oxygen. A preferred composition corresponds to the formula MgSiN2-xOx, where x is smaller than 0.5. The manufacture of the ceramic body in accordance with the invention is simpler and cheaper than that of aluminium nitride, and a number of properties of said ceramic material are better than those of the known aluminium oxide.
