    摘要: A method for producing a nitride semiconductor, comprising controlling temperature and pressure in a autoclave containing a seed having a hexagonal crystal structure, a nitrogen element-containing solvent, a raw material substance containing a metal element of Group 13 of the Periodic Table, and a mineralizer so as to put said solvent into a supercritical state and/or a subcritical state and thereby ammonothermally grow a nitride semiconductor crystal on the surface of said seed, wherein the crystal growth rate in the m-axis direction on said seed is 1.5 times or more the crystal growth rate in the c-axis direction on said seed. By the method, a nitride semiconductor having a large-diameter C plane or a nitride semiconductor thick in the m-axis direction can be efficiently and simply produced.

    摘要: A process for the production of calcium bromide from feed brines, particularly from Dead Sea End Brine (EB), is described. The process comprises extracting the feed brine in countercurrent with a composite organic solvent; optionally, purifying the extract to increase the ratio Br:Cl by contacting it with a part of the product; and washing the purified extract with water to yield the product, that is an aqueous solution of CaBr2. The composite solvent comprises an anionic extractant, such as an amine or a mixture of amines; a cationic extractant, such as a carboxylic phosphoric or sulphonic acid or a mixtures of said acids; and diluent/modifier, which is an organic solvent. An apparatus for the production of calcium bromide is also described, which comprises: an extraction battery; optionally, a purification battery; and a washing battery, wherein at least one of the batteries comprises a plurality of stages.

    摘要: The gas stream obtained from the pyrolysis of solid organic wastes and containing halogens, particularly chlorine in the form of the corresponding hydrogen halide is processed to obtain a halide free pyrolytic oil. The gas stream after solids removal is contacted with a solid metal halide acceptor above the dew point of pyrolyzate to form the corresponding metal halide which may be discarded. As an alternative the metal halide can be treated to release the hydrogen halide which is recovered as an acid and the acceptor regenerated for recycle. The preferred acceptor is calcium carbonate.
