  • In situ production of silicon carbide-containing ceramic composite powders
    Patent number: 5455212
    Abstract: A method for producing alumina-silicon carbide ceramic powders by in situ production of silicon carbide particles by introducing a pyrolyzable carbon source, preferably a gaseous hydrocarbon, into a reactor containing an alumino-silicate, pyrolyzing the pyrolyzable carbon source to form carbon particles in situ, wherein the carbon particles are capable of reacting with a silicate in the alumino-silicate to form carbide products, and then reacting the silicate and the carbon particles in situ at an effective temperature, preferably at least 1450.degree. C. and more preferably at least 1500.degree. C., for a sufficient time to transform the alumino-silicate and the pyrolyzable carbon source into the composite ceramic powder having alumina (Al.sub.2 O.sub.3) and silicon carbide (SiC) as major phases.

  • Boron isotope separation using continuous ion exchange chromatography
    Patent number: 5443732
    Abstract: This invention relates to a process of and apparatus for the continuous and selective separation of boron-10 (B.sup.10) isotope having high neutron capture cross-section from boron-11 (B.sup.10) isotope from a mixture of boron isotopes in a boric acid solution by using a weak base ion exchange resin and water eluant in a continuous annular chromatograph.
