    Abstract: An improved method of rapidly forming halide glass wherein the heating and cooling schedule has two phases of heating and cooling. This improved method substantially limits the loss of volatile components because of the significantly shortened interval of time at the elevated melting temperatures. The average time under heating is about 80 minutes. Cooling is as rapid as possible. The homogenization occurs above 800.degree. C. for about 20 minutes.

    Abstract: A method for the manufacture of a preform of barium containing heavy metal fluoride glass comprising a core and a jacket for drawing infrared light waveguides for optical communications technology by casting molten glass onto a predetermined body of solid glass. Hitherto, such a method was executed such that molten core glass was cast into a tube of jacket glass. In order to achieve thicker preforms, one proceeds such here that a solid row of the core glass is surrounded with molten jacket glass. The boundary surface between core and jacket of the generated preform can be improved in the method disclosed herein that the surface of the solid rod is etched before being surrounded with the jacket glass. A nearly perfect boundary surface is obtained by etching with a ZrOCl.sub.2 solution.

    Abstract: PURPOSE:To produce a thin membrane of the fluorinated amorphous material capable of utilization as the infrared optical material by mixing the respective fluorides of Ba, Sr, Ca, Li and Al in the specified proportion, making the melt thin membrane-like and ultraquenching it. CONSTITUTION:In a formula xMF2.yLiF.zAlF3 (x+y+z=1), the mixture is melted wherein the component M is at least one kind of metallic fluoride selected among Ba, Sr and Ca and it consists of the composition of the compo nent range of x=0.2-0.6 y=0.2-0.6 z=0.1-0.4. Then this melt is sent between the metallic rollers to ultraquench it and made to a thin membrane body (about 60mu thickness) having the uniform membrane thickness. Thereby the amorphous material excellent in the infrared rays permeability is obtained.
