    Determination of the observation conditions of celestial bodies with the aid of the DISPO system (1984)
    In:  CASI
    Details
    Publication Date: 2019-08-28
    Description: The interactive system for determining the observation conditions of celestial bodies is described. A system of programs was created containing a part of the DISPO Display Interative System of Orbit Planning. The system was used for calculating the observatiion characteristics of Halley's comet during its approach to Earth in 1985-86.

    Study of the pore structure of ceramics prepared by the slip casting method (1984)
    In:  CASI
    Details
    Publication Date: 2019-08-28
    Description: The porosity of the slip cast Si3N4 is similar to that of pressed Si3N4 formed at 2500 kg/sq cm. The porosity of cast Si oxynitride is equivalent to that of samples stressed at 10,000 kg/sq cm. Crucibles formed from these materials by slip casting have high thermal shock and corrosion resistance.

    Zeta potential in ceramic industry (1984)
    In:  CASI
    Details
    Publication Date: 2019-08-28
    Description: Deflocculation, electrical conductivity and zeta potential (ZP) are studied for the addition of 0 to 10000 ppm Na2SiO3 deflocculator to slips obtained from three argillaceous materials (kaolin d'Arvor, ball clay Hyplas 64, and/or Granger Clay No. 10). The quantity of Na2SO3 required to deflocculate a slip is independent of the density but differes for each clay. The ZP is directly related to the density of the slip. The higher the ZP the more stable a slip is; the value of the ZP of a mixture does not follow a simple law but the electrical resistance of a mixture does follow a simple additive law. The ZP appears to have linear relation with the specific surface of the argillaceous material.

    The colloidal chemistry of ceramic clays (1984)
    In:  CASI
    Details
    Publication Date: 2019-08-28
    Description: The colloidal chemistry and mineralogy of two argil minerals were studied. Deposits of kaolin and of ceramic clays in the United States and England are discussed for the probable mechanism of formation. The structural modifications of the bed, original material associated with the clays and the proper use of flocculants are discussed.

    Microstructure of ceramics fabricated by unidirectional solidification (1984)
    In:  CASI
    Details
    Publication Date: 2019-08-28
    Description: The unidirectional solidification methods are zone melting, crystal pulling, Bridgemen, and slow cooling. In order to obtain excellent properties (such as transparency), pores, voids and cracks must be avoided, and elimination of such defects is described.
