Abstract

922,521. Electrolytic deposition of hydroxides. GENERAL ELECTRIC CO. Feb. 17, 1960 [March 5, 1959], No. 5624/60. Class 41. Silicon sheet steel material is insulated by making it the cathode in electrolysis of a salt of a metal forming an insoluble hydroxide so that the hydroxide is deposited on the material, and then heating the material so as to cause the hydroxide to react with the silicon in the steel to form a refractory insulating silicate coating. In examples, solutions of (1) calcium nitrate, (2) magnesium nitrate, (3) calcium and aluminium nitrates, (4) calcium and magnesium nitrates, and (5) manganese sulphate are used as electrolytes, and the hydroxide-coated steel is then annealed in hydrogen at 1175‹ C. for several hours.
