    摘要: A method for making a gradient index infrared transmitting optic by thermally treating a preform, where the preform comprises two or more infrared transmitting glasses having different compositions and optical properties, where there is an interface between adjacent glasses, where during the thermal treatment one or more chemical elements from the glasses diffuses through one or more interface resulting in a diffused gradient index optical element comprising a gradient in the chemical element concentration, and where the optical element has a gradient in refractive index and dispersion. Also disclosed is the related infrared transmitting optical element made by this method.

    摘要: There is disclosed a process for preparing a thallium-containing superconductive composition. In the first step of the process, a mixture of an inorganic salt (such as potassium chloride) and a powder compositon is provided; the powder composition contains at least three separate compounds which, in combination, correspond to the stoichiometry of the super-conductor to be produced. This mixture is then charged to a closed container, raised to a temperature of from 800-959 degrees Centigrade, and heated for from about 1 to about 12 hours; thereafter, it is cooled to a temperature of 600 degrees Centigrade at a rate of at least 300 degrees Celsius per hour.
