Abstract:
A process of preparing polycrystalline group III nitride chunks comprising the steps of (a) placing a group III metal inside a source chamber; (b) flowing a halogen-containing gas over the group III metal to form a group III metal halide; (c) contacting the group III metal halide with a nitrogen-containing gas in a deposition chamber containing a foil, the foil comprising at least one of Mo, W, Ta, Pd, Pt, Ir, or Re; (d) forming a polycrystalline group III nitride layer on the foil within the deposition chamber; (e) removing the polycrystalline group III nitride layer from the foil; and (f) comminuting the polycrystalline group III nitride layer to form the polycrystalline group III nitride chunks, wherein the removing and the comminuting are performed in any order or simultaneously.

Claim (Index 7):
The plurality of polycrystalline group III nitride chunks of  claim 1 , wherein each of the plurality of polycrystalline group III nitride chunks has a concentration of oxygen as a group III oxide or as a substitutional impurity less than about 3 parts per million, and a concentration of silicon present as a substitutional impurity less than about 3 parts per million.
