| 1. A method of siloxyl coating metallic particles, comprising the steps of:
mixing metallic particles with a silane solution to yield a metallic particle-silane solution mixture;
creating a suspension of said metallic particle-silane solution mixture for a first period of time to yield siloxyl coated
metallic particles;
separating said siloxyl coated metallic particles from said silane solution;
rinsing said siloxyl coated metallic particles with an organic solvent to yield purified siloxyl coated metallic particles;
drying said purified siloxyl coated metallic particles;
mixing said dried and purified siloxyl coated metallic particles with a cross linking solution to yield a siloxyl coated metallic
particle-cross linking solution mixture;
creating a suspension of said siloxyl coated particle-crosslinking solution mixture for a second period of time to yield siloxyl
coated and cross linked metallic particles; and
separating said siloxyl coated and cross linked metallic particles from said cross linking solution.
