Abstract
LMSC Glass-Like Carbon is one of the newer forms of hard, impervious, and nongraphitizing-type carbons. It is a monolithic form of carbon produced from the degradation of an organic polymer. The precursor polymer employed can be modified substantially to produce variations in the carbon structure. The carbon end use is analyzed to determine the best precursor resin. The property similarities between this material and glass are high tensile strength, high compressive strength, low permeability, isotropic characteristics, and low impact strength. However, since the material is a pure carbon, the high- temperature properties are substantially higher than those of glass. Tensile strength at 2500C is double the room temperature values. Preliminary studies indicate long-term stability at 1000F in air. As a new high-temperature structural material and an improved carbon product, LMSC Glass-Like Carbon offers many advantages. Current applications include high-temperature reaction vessels, crucibles, resistance elements, induction susceptors, and electrodes.
