The use of Phosphorus for the growth of III-V and other electro-optic materials requires a higher purity than presently available commercially. Parke Mathematical Laboratories, Inc. proposes to develop the ultra-purification of red phosphorus and commercialize the purified phosphorus at a very low cost. This proposal outlines the sublimation technique used in the Phase I part of this SBIR contract to improve the purity of red phosphorus as an element. The purity was improved by several orders of magnitude. The cost of material produced by this process is probably about a quarter of the cost of the electronic grade material. An additional factor is that while this material would be produced in the U.S.A., there is presently no supplier of high grade phosphorus in this country. In Phase III we propose to team up with a chemical manufacturer based U.S.A. and produce electronic grade red phosphorus.
