Cylindrical molybdenum samples 0.05" diameter by 5" long, 0.10" diameter by 5" long, 0.375" diameter by 4" long and 1.75" diameter by 3" long were heated in inert atmospheres to various temperatures up to 2290 F and plunged into liquid oxygen. All samples heated to temperatures below 1600 F quenched with substantially no weight loss. For high temperatures, samples up to 0.375" diameter behaved differently than the larger samples, in that once ignited they burned until completely consumed. Samples of 1.75" diameter failed to support combustion even when heated to 2100 F. These larger samples quenched after a small percentage …

Description
Cylindrical molybdenum samples 0.05" diameter by 5" long, 0.10" diameter by 5" long, 0.375" diameter by 4" long and 1.75" diameter by 3" long were heated in inert atmospheres to various temperatures up to 2290 F and plunged into liquid oxygen. All samples heated to temperatures below 1600 F quenched with substantially no weight loss. For high temperatures, samples up to 0.375" diameter behaved differently than the larger samples, in that once ignited they burned until completely consumed. Samples of 1.75" diameter failed to support combustion even when heated to 2100 F. These larger samples quenched after a small percentage weight loss. Small molybdenum bars, 2 by 5 millimeters protected by an inert metallic coating ignited occasionally in liquid oxygen when heated above the melting point of the coasting (approximately 1950 F). Larger partially coated cylindrical samples 1.75" diameter by 3" long quenched in liquid oxygen after a small amount of reaction which was approximately proportional to the area of molybdenum exposed.
