NOVELTY - The procedure for cleaning metallurgical silicon melt (1) useful for the production of electronic devices, electronic components and solar cells, comprises constantly passing successive cleaning zones (3) through the melt transferring against each other in repeated manner, and developing temperatures in the cleaning zones. The cleaning zones are formed by local cooling and heating of the melt and are held at 1420-1470 degrees C during the cleaning. The melt partially solidifies in the cleaning zones. The melt in a crucible (5) is moved by several cooling zones (7, 9) and heating zones (8, 10).    USE - Procedure for cleaning metallurgical silicon melt (claimed) useful for the production of electronic devices, electronic components and solar cells.    ADVANTAGE - The procedure ensures economical and efficient cleaning of silicon melt with 100% purity, high throughput and less-energy consumption in less-time consuming manner.    DETAILED DESCRIPTION - The procedure for cleaning metallurgical silicon melt (1) useful for the production of electronic devices, electronic components and solar cells, comprises constantly passing successive cleaning zones (3) through the melt transferring against each other in repeated manner, and developing temperatures in the cleaning zones. The cleaning zones are formed by local cooling and heating of the melt and are held at 1420-1470 degrees C during the cleaning. The melt partially solidifies in the cleaning zones. The melt in a crucible (5) is moved by several cooling zones (7, 9) and heating zones (8, 10), which are moved along to the crucible containing the melt. Cooling devices arranged in the surroundings of the crucible are activated for the local cooling and heating of the melt. Heating devices arranged in the surroundings of the crucible are switched-off or downwardly adjusted and again connected or upwardly adjusted and/or connected or downwardly adjusted and again switched-off or upwardly adjusted for the formation of the cleaning zones in temporarily shifted manner. The temperature possibly lies close to its melting temperature of the melt. An INDEPENDENT CLAIM is included for a device for cleaning metallurgical silicon melt.
