    摘要： The present invention pertains to the use of an additive selected from the group consisting of amorphous silica, graphite powder, and a mixture thereof in a process to electroplate or electropolish a metal on a substrate using an ionic liquid as the electrolyte to increase metal layer thickness. It furthermore pertains to a method to electroplate or electropolish a metal on a metal substrate wherein an ionic liquid is employed as electrolyte, wherein a metal salt added to said ionic liquid or a metal anode is employed as metal source, and wherein said ionic liquid comprises said additive.

    摘要： The present invention pertains to a process to make salt compositions comprising the steps of - feeding water to a salt source to form an aqueous solution comprising said salt, - feeding said aqueous solution to a crystalliser/settler, - contacting said aqueous solution with one or more antisolvents which force the salt to crystallise, with said antisolvents exhibiting crystal growth inhibiting properties and/or crystallisation and scale inhibiting properties, and/or where one or more crystal growth inhibitors are present either in the antisolvents or the aqueous solution and/or one or more scaling inhibitors are present either in the antisolvents or the aqueous solution, - feeding an overflow of the crystalliser/settler comprising one or more antisolvents and an aqueous salt solution to a nanofiltration unit comprising a membrane to separate the one or more antisolvents from the aqueous salt solution, - removing the crystallised salt in an aqueous slurry, - optionally, recycling the one or more antisolvents to the crystallises/­ settler, and - optionally, recycling water from the slurry to the first dissolution step and/or to the crystallises/settler. Preferably, the process is a closed loop process and the salt is sodium chloride. Preferably, the process further comprises a reverse osmosis step before the overflow of the crystallises/settler is fed to a nanofiltration unit.
