This class of materials can be used to trap micrometeorites in outer space before they are burnt up by the earth's atmosphere, and transparent tiles formed from it can take the place of compressed gases or low-density liquids in Cherenkov detectors.

This class of materials can be used to trap micrometeorites in outer space before they are burnt up by the earth's atmosphere, and transparent tiles formed from it can take the place of compressed gases or low-density liquids in Cherenkov detectors. Five times more effective as insulators than polystyrene, liquid carbon dioxide was used instead of alcohol during the production process after a factory accident in 1984.  FTP, identify these materials discovered in the 1930s when chemist Samuel Kristler attempted to dry wet silica gels without shrinking them.
