Gilsonite Properties

Gilsonite Properties

Gilsonite greatly resembles asphalt. of which it is considered a species by many authors. Asphalt readily becomes softened by the warmth of the hand or the rays of the sun.

Gilsonite is not affected by heat below the boiling point of water.

Gilsonite does not have the same melt point, varying widely from about 230° F to 500° F, depending upon the particular vein from which the sample has been taken. Some of the larger veins contain more than one type of Gilsonite. giving evidence of the vicissitudes that have affected the material during vein filling. polymerization and weathering.

Gilsonite  When fused melts like tar and seals out the air that would support combustion.

Gilsonite having a melting point of approximately from 150C up to 220. (Ball and Ring method) and ash of solved and, therefore, is poorly suited as a saturating material for brake linings for instance, where a considerable proportion of the colloidal material is left on the surface when impregnation is attempted.

Gilsonite is completely dissolved in the ordinary solvents such as gasoline or benzol unless, for instance, it is refluxed with these solvents at a high temperature. This is probably due to the fact that Gilsonite is highly colloidal and therefore, tends to resist complete smooth solution

Gilsonite being a natural material varies in composition depending upon its origin, history of formation and the geographical region and the presence of other minerals such as sulphur, phosphorus, and others. So little wonder Gilsonite does not have a specific composition.

Gilsonite is available in different grades categorized by softening point. The softening point is used as an approximate guide to melt viscosity and behavior in solution.
