Abstract
1. Способ получения слитков чистого кремния из порошка кремния, отличающийся тем, что упомянутый порошок вместе с газом-носителем пропускают через слой расплавленного кремния. ! 2. Способ по п.1, отличающийся тем, что в качестве газа-носителя используется увлажненный газ, например, азот. ! 3. Способ по п.1, отличающийся тем, что расплав кремния поддерживают при температуре выше 1600°С. 1. A method of producing pure silicon ingots from silicon powder, characterized in that said powder together with a carrier gas is passed through a layer of molten silicon. ! 2. The method according to claim 1, characterized in that a humidified gas, for example nitrogen, is used as a carrier gas. ! 3. The method according to claim 1, characterized in that the silicon melt is maintained at a temperature above 1600 ° C.
