title: Reflection and polarization properties of powder materials.
abstract: Directional radiance factors and polarization are presented for pure silicon carbide powder with an average albedo of 0.15 over a size range from 8 micro to 86 micro, pure aluminum oxide powder with average albedo about 0.85 over a size range from 0.1 micro to 86 micro, and for a mixture of one part silicon carbide to six parts aluminum oxide with average albedo of about 0.40 over a size range from 5 micro to 86 micro.
