Abstract
Disclosed is a method to synthesize Si.sub.3 N.sub.4 from SiX.sub.4 +NX.s3, wherein X is selected from hydrogen and/or fluorine, by laser photochemical reaction (LPR) technique in a controlled atmosphere chamber wherein the reactant gases are maintained at pressures between about 10 and about 200 torr in a molar volume ratio of about 3 of the SiX.sub.4 to about 4 of the NX.sub.3. The LPR method produces the compound Si.sub.3 N.sub.4 at room temperature while employing a pulsed laser or a continuous wave laser.
