Abstract
This invention refers to improvements to thermoelectrical insulation for high temperatures and electric currents manufactured from amorphous natural graphite, and more specifically to a procedure that consists of the grinding, mixing and classifying by particle size the raw graphite previously selected on the basis of its components of carbon-ash, from which the final product is obtained.
Claims5
The method of manufacturing insulation from amorphous natural graphite comprising the steps of:
- isolating graphite particles no longer than six inches in diameter with an ash content between 25% to 40%,
- separating the particles into three sizes, namely:
- (a) those from three to six inches in diameter, (b) those between one and a half to three inches in diameter, and (c) those less than three inches in diameter,
- establishing respective ash and carbon contents of the respective sized particles, and
- mixing the three sized particles in a proportion for meeting an insulation product specification.
