    Abstract: The present invention relates to an orthogonal-phase compound and its nonlinear optical (NLO) crystal of BaGa7Se7, its producing method and uses thereof. Polycrystalline orthogonal-phase BaGa4Se7 was prepared by a high-temperature solid-phase reaction in a sealed silica tube.

Orthogonal-phase BaGa4Se7 has a powder second harmonic generation (SHG) efficiency of about 5 times that of AgGaS2 and is phase-matchable. The orthogonal-phase BaGa4Se7 is non-hygroscopic and has good mechanical properties, which makes it easy to cut, polish, and coat by normal processing.

  • Patent number: 12116273
    Abstract: The objective of the invention is the development of a new process for producing sulfur from phosphogypsum. During this process, the phosphogypsum is mixed with a source of carbon and hydrogen forming a slurry after mixing. This source of carbon and hydrogen is a natural or synthetic organic polymer, as an example that is not limiting, biomass, used tires or plastic, kerogen or tars. The granules undergo a heat treatment (100 to 150° C.) to evaporate the mixing water. The product obtained undergoes a heat treatment (550 to 900° C.) under a neutral atmosphere and/or partially oxidizing. The generated gases are bubbled in deionized water, sodium hypochlorite solution or a basic aqueous solution which allows the trapping, among others, of organosulfur molecules and the precipitation of sulfur S8. Non-entrapped gases are recovered to extract volatile sulfur products.
