Pump that can move molten metal at record 1,400ÂºC made
US-based researchers have designed a ceramic-based mechanical pump that can operate at record temperatures of over 1,400ÂºC and transfer liquids like molten tin. The pump operated for 72 hours continuously at a few hundred revolutions per minute at 1,200ÂºC, with brief runs at 1,500ÂºC also. It could facilitate high efficiency, low-cost thermal storage for renewable energy, said the researchers.
