    摘要： A process for producing KNO3 from polyhalite is disclosed. In a preferred embodiment, the process comprises steps of (a) contacting polyhalite with HNO3; (b) adding Ca(OH)2 to the solution, thereby precipitating as CaSO4 at least part of the sulfate present in said solution; (c) precipitating as Mg(OH)2 at least part of the Mg2+ remaining in said solution by further addition of Ca(OH)2 to the remaining solution; (d) concentrating the solution, thereby precipitating as a sulfate compound at least part of the sulfate remaining in solution; (e) separating at least part of the NaCl from the solution remaining; and (f) crystallizing as solid KNO3 at least part of the K+ and NO3- contained in the solution. The process enables direct conversion of polyhalite to KNO3 of purity exceeding 98.5% and that is essentially free of magnesium and sulfate impurities.

    摘要： A water-soluble insert for use in joining pipes, made of a material comprising a salt selected from the group consisting of KCl, Na Cl, and mixtures thereof; and MgO. Upon addition of a small amount of water to the material, the MgO reacts with hygroscopic impurities in the chloride salt to provide a material with superior properties. The insert is cast from the material, in general by being placed on a form and compressed. Also disclosed is the use of the insert in joining the ends of two pipes, especially pipes made from thermoplastic. The insert is placed in the matching pipe ends, which are then welded. After the join is complete, water is flowed through the pipe, dissolving the insert.
