Abstract: Particulate, active-oxygen compounds, especially sodium percarbonate, tend to cake during storage, which makes it more difficult to handle them. The invention reduces this caking tendency while the active-oxygen content remains essentially unchanged. The method of achieving this comprises bringing the active-oxygen compound in contact with such an amount of an aqueous solution containing one or more phosphonic acid compounds capable of chelate complex formation that the weight ratio of active-oxygen compound to phosphonic acid compound is 100:0.1 to 100:10, preferably 100:1 to 100:3, and subsequent drying. Sodium percarbonate is used in particular as active-oxygen compound and 1-hydroxyethane-1,1-diphosphonic acid as a 3 to 30% by weight aqueous solution is used as phosphonic acid compound. Sodium percarbonate wet salt is preferably washed with this solution, freed of excess solution and dried. Percarbonate treated in this manner hardly tends to cake at all and exhibits a greater active-oxygen stability.

Abstract: The deposition is performed in a reactor in which the substrates have their main surface parallel to the gasflow direction. The quartz-reactor (1) is surrounded by a pref. also quartz, protective tube (2). Via a flange, pref. ground glass, fitting (3,4) the depsn. tube is attached to the gas-inlet (5) made in the protection tube. A gas-inlet (6) in the outer tube ensures that the space between the 2 tubes is flushed. The gas flows out of the tube, together with the reactor-gas, via an outlet (7). A diffusion barrier is present in the reactor-tube end. The substrate surfaces to be coated are pref. flush with the wall of the flange (3), by the use of a susceptor (11). The susceptor (11) pref. only extends through part of the tube and a compensating part (12) is inserted which covers the space from the end of the susceptor to the end of the tube. This part (12) has an outlet (13) which fits over the outlet (7) in the outer tube. The height of the reactor tube reduces towards the end, to form the diffusion barrier, to the height of the compensation part (12). The transition of high to low part of the tube occurs via a panel (14) fitted above the outlet. The outer tube has a flange (8) at the end opposite to the gas-inlet, on which a plate (9) fits to seal the tube. Pushrods are fitted in this plate which ensure correct positioning of susceptor and reactor tube. The reactor uses for deposition of III-V and II-VI cpds. gasflow rates of up to 20 m/sec. at pressures of 10-1000 mbar.
