Abstract:

This publication is intended to provide a convenient source of reliable, up-to-date property data on nitride ceramics for use in engineering work. Its issuance constitutes completion of the first phase in a program to update and upgrade the Databook Engineering Properties of Ceramics which was issued in 1966 both as AFML-TR-66-52 and as an American Ceramics Society publication. The nitrides are compounds of other elements with nitrogen. The more common of the single nitrides are those of aluminum, boron, silicon, hafnium, titanium, zirconium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, thorium, plutonium, and uranium. Of these boron nitride BN and silicon nitride Si3N4 are presently most important in engineering usage and have received greatest attention in ceramic development. Properties of the nitrides as presented are generally divided into the categories of physical, thermal, mechanical, and chemical. The physical properties include crystal structure, density, and melting or sublimation point. The thermal properties include specific heat, thermal conductivity, and thermal expansion. The mechanical properties include strength, elastic modulus, hardness, creep, and fracture mechanics parameters. The chemical properties include oxidation and corrosion resistance data, and general compatibility information.
