Abstract
A heat transfer liquid in the form of a molten salt mixture includes a mixture of potassium nitrate and lithium nitrate, and added calcium nitrate and/or anhydrous salts if appropriate. This is done in order to achieve a low melting point, a low toxicity and in particular a low viscosity. The heat transfer liquid may be used in the vulcanization of rubber.
