file icon Ultrahigh-Temperature CeramicsTooltip 09/01/2007 Hits: 59
NASA Ames is developing a subset of UHTC materials consisting primarily of Hafnium and Zirconium Diboride (HfB2 and ZrB2) ceramics. The diborides have extremely high melting temperatures (3000 deg C) and have relatively good resistance to oxidation in simulated reentry environments.
Emulsified iron is injected into the ground and left there.
