Hot-pressed molybdenum disilicide bodies produced by industrial methods and sources were evaluated. The outstanding characteristics reported are an elevated-temperature (2400 degrees F) short-time tensile strength of 41,070 pounds per square inch and an 100-hour rupture stress at 1800 degrees F in excess of 30,000 pounds per square inch, as indicated in a preliminary evaluation. The material evaluated was extremely resistant to air corrosion up to 2850 degrees F and generally brittle at temperatures below 2200 degrees F,
