Looking for something special in materials? Norton high-purity, high-stability materials aid in solving many industrial problems . . . like these
In Supersonic Flight. Marquardt Aircraft Company of Van Nuys, Cal., uses Norton ROKIDE* protective coating in its new, highly advanced ramjet engines for supersonic missiles. The flame-sprayed ROKIDE aluminum oxide coating greatly increases the tailpipe's resistance to excessive heat and erosion. Other ROKIDE coatings for high temperature applications include " Z S " zirconium silicate and " Z " stabilized zirconia.
If lack of suitable materials is delaying development or improvement of your products, remember this: Norton high-melting, fusionstabilized materials have helped solve many such problems for manufacturers, in applications ranging from home appliances to guided missiles and atomic energy equipment. Here is a partial list of Norton refractory materials: ALUNDUM* fused alumina, CRYSTOLON* silicon carbide, MAGNORITE* fused magnesia, N O R BIDE* boron carbide, fused stabilized zirconia, special fused oxides, refractory carbides and borides. Another point to remember: these materials offer you combinations of thermal, electrical and physical characteristics not available in the usual refractory substances. Melting points range up to 6400°F. Electrical resistance and thermal conductivity run from low to very high. NORBIDE boron carbide, with a Knoop hardness of 2800, is the hardest commercial material made by man. Norton high-melting materials are the basic ingredient of the famous Norton Refractory IJ's — refractories engineered and prescribed for the widest range of industrial uses. Norton Company supplies them in crude, processed or fabricated form, and will work with you in engineering them to your requirements.

After inventing their outstanding new RF induction lamp, Sylvania Electric Products Inc. turned to Norton Company as a dependable source of high-melting, stable materials. Norton tantalum carbide was selected as the lightemitting source. Heated to a much higher temperature than tungsten filaments can stand, this material becomes the most uniform concentrated light source ever developed.
