A survey was made on the chemical, physical, and technological properties of the elements, metals, and compounds considered to have considerable future prospects for utilization in silicate technology. Sections are devoted to the properties of the following elements and their compounds: lithium, beryllium, strontium, zirconium, hafnium, thorium, tantalum, niobium, and the rare-earth elements. Data are tabulated for specific gravity, melting point, coefficient of expansion, heat conduction, specific electric resistance, microhardness, and modulus of elasticity for the relatively new refractory zirconium compounds, ZrC, ZrN, ZrB/sub 2/, and ZrSi/sub 2/; the specific gravity, crystal lattice system, lattice constant, melting point, boiling point, coefficient of linear expansion, and neutron absorption for tantalum and niobium; and the melting point, boiling point, specific gravity, coefficient of linear expansion, magnetic susceptibility, thermal neutron capture cross section, oxide obtained from ignition in air, and melting point of the oxide for the rare earth metals. 111 references are included.
