    Abstract: Ultrasharp diamond edges and points which are usable as high intensity point sources for the emission of electrons, ions, X-rays, coherent and incoherent light and high frequency electromagnetic radiation are produced by preparing and classifying ultrafine diamond powder having a particle size of 10 to 100 angstroms, placing the powder in a diamond mold defining the ultrasharp edge or point to be produced and applying a pressure of the order of 80 to 90 kb while heating the powder to a temperature of the order of 2440.degree. K. in an ultrahigh vacuum or inert atmosphere after degasing to avoid oxidation of the diamond powder.
