AbstractIt has been possible, with certain types of refractories, to apply phase‐rule data to the manufacturing processes. The fields in which these data are useful include silica, magnesite, chrome, dolomite, forsterite, and, to a limited extent, alumina‐silica refractories. Phase‐rule data frequently are inadequate, and in other cases their use is dependent on certain empirical generalizations. Refractories usually contain five or more oxides which are present in amounts that cannot be ignored. The application of three‐component phase‐rule data is possible because of independent research conclusions which have shown that there is almost no solubility of certain components in the liquid phase in some systems or that one or more components are present almost entirely in solid solution.In predicting which of several types of refractories is likely to succeed best in a given service, the information available is usually insufficient to permit a strict application of phase‐rule data. Slagging action, in a large measure, depends on slag viscosity, and viscosity data are usually no

摘要:

AbstractElectrodialyzed samples of several clays were saturated at pH 7 with various cations, and measurements were made to determine the effect of these cations on the workability and drying behavior of the clays. Excellent correlations were noted between the influence of these ions on clays in the plastic state and their behavior in causing flocculation or denocculation of dilute suspensions of clay. The results should be valuable for such industrial forming processes as throwing, jiggering, hot pressing, and extruding.

摘要:

AbstractThe particle‐size distributions of experimental and commercial stains and glazes and glaze materials were determined by using the Andreasen pipette method. The variation in particle size of two porcelain glazes, raw and fritted, was correlated with the glaze working properties and certain physical properties of the glaze film, such as fluidity, microtexture, scratch‐hardness, and glaze stress. The relation of grinding efficiency to length of milling time and different ball size was studied for these two glazes and also for a stain, and the color imparted by the stain at different grain sizes was no

摘要:

AbstractThe effect of variations in the particle size of typical green and blue color stains in sized fractions of a representative clear frit was studied. Microscopic examinations were made of the sized fractions, and photomicrographs of the respective fields are presented. The color characteristics of the enameled panels were determined on a continuously recording spectrophotometer. Frit particles of 45 to 75 μ, combined with color particles of less than 5μ, were found to give the optimum or most efficient color characteristics, and color particles larger than 5 μ, seriously impaired the resulting col
