    The flame propagation rates of two lightweight materials, beryllium and silicon nitride, were evaluated in oxygen using the upward flammability ASTM promoted combustion test method. Beryllium was found to be self-extinguishing up to 3.5 MPa (500 psia). Silicon nitride was found to be self-extinguishing up to 69 MPa (10000 psia). Comparison of these experimental results with those obtained for 6061 aluminum, 7% aluminum bronze, and various steel and nickel alloys, using the same test method, is provided.
