    摘要: Glassy coatings that isolate metal surfaces from carbon particles, and a method of applying the coatings. The coatings composed of essentially K2O, SiO2, and Al2O3, and has a CTE of at least 80 x 10-7/°C. These glassy coatings, which adhere well to metals, employ a potassium-silicate glass composition in three forms: a pure glass, a glass loaded with inert filler having a CTE higher than the glass itself, and a precursor frit that when 'reactive-cerammed' produces a predominantly leucite crystalline phase and forms the glassy coating in-situ on the metal surface, creating a protective layer between the exposed metal surface and corrosive chemical-processing environments.

    摘要: A method of controlling the rheology of a sealing glass paste which comprises incorporating a fine inorganic powder in the paste as a mill addition to impart a steep rheology curve to the paste so that the paste resists flow while at rest, but flows readily when shear stress is applied, the amount of inorganic powder incorporated being not over about 10 % by weight. The figure, shows a graphical representation of the invention as applied to a non-lead sealing glass.
