摘要

The method for increasing viscosity of a metal melt in a composition, comprises adding a powder from a material to the metal melt, where the powder has a melting point for superficially alloying with components of the metal melt. The melting point of the powder is above the melting temperature of the metals of the metal melt, so that the powder does not melt in the melt. The melting temperature is 100-900[deg] C. The powder contains particles, which have an average particle size of 1-100 mu m, are spherical, plate-shaped, fibrous or dendritic and present as mixture of different shaped particles.

The melting point of the powder is above the melting temperature of the metals of the metal melt, so that the powder does not melt in the metal melt. The melting temperature is 100-900[deg] C. The powder contains particles, which have an average particle size of 1-100 mu m, are spherical, plate-shaped, fibrous or dendritic and present as mixture of different shaped particles. The material for the powder is electrically conductive. The portion of powder in the metal melt is 1-80 vol.%. The mixing of the metal melt and the powder is carried out in an injection molding machine. An independent claim is included for a composition containing a metal melt with low melting point and a powder with a melting point.
