CARBO ceramic media is engineered with unique thermal, physical and chemical properties that excel at absorbing heat at high temperatures without breaking down.
Read full article on Sandia’s continuously recirculating falling-particle receiver emplaced at top of solar tower and "enable higher temperatures and higher efficiency power cycles that will bring down the cost of electricity produced from concentrating solar power." Utilizing ceramic media technology "can capture and store heat at high temperatures without breaking down, unlike conventional molten-salt systems."
