Abstract: A solid state combinatorial synthesis of particulate diamond ranging in size from the macroscopic down to the nanoscale, which entails: a) forming a solution having a source of reactant atoms, a tetrahedranoidal compound reactant, and a solvent vehicle; b) forming liquid droplets of the solution; c) evaporating the solvent vehicle from the liquid droplets of the solution to form particles containing a homogenous solid mixture of the reactants; and d) exposing the particles of the homogeneous solid mixture to a high energy discharge thereby forming diamond particles.

Abstract: A combinatorial synthesis of a heterodiamond unit cell, which entails a step of reacting a tetrahedranoidal molecule with a heteroatom to form heterodiamond unit cell and then heterodiamond mass.

Abstract: An apparatus for forming diamond, which contains a reaction chamber, means for providing tetrahedranoidal reactant molecules to the reaction chamber; and means for providing single carbon atoms in the reaction chamber to provide for reaction between the single carbon atoms and tetrahedranoidal reactant molecules.

Abstract: Methods and apparatus are disclosed for producing diamond masses and products thereof using diamond unit cell forming reactions in vapor phase and solid phase. The present invention enables the fabrication of diamond products having a purity and morphology previously unattainable.
