Book Description
The objective of this research program was to evaluate the feasibility of coating the propellant surface with an opaque, nonreacting material to eliminate this difficulty in interpretation of test results. The effect of the coating would be to reduce absorption of radiant energy beneath the propellant surface and provide a uniform surface absorptivity for different propellants. Radiant flux levels considered for this study were selected to indicate the effectiveness of coatings over a range of 30 to 130 cal/sq cm -sec. Both rubber-base and double-base propellants were tested. Results of this program indicate that zirconium carbide and tungsten carbide can be used as nonreactive coatings in arc-image furnace testing. However, certain anomalies were observed that might indicate that propellant ingredients and coating materials can interact and influence the ignition energy requirements in specific heating ranges.

Book Description
This publication presents cleaning and etching solutions, their applications, and results on inorganic materials. It is a comprehensive collection of etching and cleaning solutions in a single source. Chemical formulas are presented in one of three standard formats - general, electrolytic or ionized gas formats - to insure inclusion of all necessary operational data as shown in references that accompany each numbered formula. The book describes other applications of specific solutions, including their use on other metals or metallic compounds. Physical properties, association of natural and man-made minerals, and materials are shown in relationship to crystal structure, special processing techniques and solid state devices and assemblies fabricated. This publication also presents a number of organic materials which are widely used in handling and general processing...waxes, plastics, and lacquers for example. It is useful to individuals involved in study, development, and processing of metals and metallic compounds. It is invaluable for readers from the college level to industrial R & D and full-scale device fabrication, testing and sales. Scientific disciplines, work areas and individuals with great interest include: chemistry, physics, metallurgy, geology, solid state, ceramic and glass, research libraries, individuals dealing with chemical processing of inorganic materials, societies and schools.
