  • Process for preparing a two phase HFB.sub.2 -SIB.sub.4 material
    Patent number: 5840367
    Abstract: A chemical vapor deposition process comprising reacting HfCl.sub.4 with Bsub.3 and SiCl.sub.4 with BCl.sub.3 on a surface heated at 1100.degree. C. to 1300.degree. C. in a vacuum to produce a two phase HfB.sub.2 -SiB.sub.4 ceramic coating on the surface, wherein the HfCl.sub.4, SiCl.sub.4, and BCl.sub.3 reactants are deposited onto the heated surface from a vapor phase, and wherein H.sub.2 is used to dissociate the HfCl.sub.4, SiCl.sub.4 and BCl.sub.3 molecules.
