    • A method for the production of a radiographic screen comprising the following steps:1) dispersing phosphor particles in an organic liquid in the presence of a charge controlling agent that charges said phosphor particles with a positive or negative net charge,2) arranging said dispersion between a pair of electrodes, wherein one of said electrodes is or carries a conductive support of said radiographic screen,3) applying and maintaining between said electrodes a sufficiently high direct current voltage to deposit charged phosphor particles onto said conductive support, and4) separating said support carrying electrophoretically deposited phosphor particles from said organic liquid,wherein the dispersing of said phosphor particles proceeds by means of an organic surface active compound acting as dispersing agent for said phosphor particles, and said phosphor particles are electrostatically charged through adsorption thereon of ionic components of said organic surface active compound and/or through adsorption of cations or anions stemming from an ionic inorganic compound incorporated in said liquid.

    • The invention relates to the production of inorganic fibers comprising a metal oxide phase and a finely divided disperse phase distributed throughout the oxide phase, the disperse phase constituting about 0.5 to 50% by weight of the fiber. The process involves preferably dry spinning a solution in water or an organic solvent of fiber forming components which, when heated to temperature of from 500.degree. to 1600.degree. C either in an inert or in a reactive atmosphere, form at least two phases with a miscibility gap, of which one phase is an oxide phase containing the other phase in very finely disperse form. Preferably, the solution contains a metal salt, the anion of which contains carbon so that upon heating there is formed an oxide phase comprising the oxide of said metal having carbon dispersed therein; if carbon is not in the anion, its precursor may be an organic compound, such as a polymer, present in the solution. Other materials which may constitute the disperse phase include boron as well as carbides, nitrides, borides or silicides and some metals. The resulting fiber are of low porosity and high modulus and impart superior properties to plastics, metals, glasses and ceramics reinforced therewith.
