Abstract: A method of providing a thin adherent electrically insulating coating on magnetic sheet material comprises the steps of applying to the sheet a layer, having a thickness of from 25 to 150 per cent of the thickness of the magnetic sheet material, of an aqueous composition comprising one part by weight of finely divided magnesium oxide, from 2 to 5 per cent of bentonite based on the weight of the magnesium oxide and from 8 to 16 parts by weight of water, and then heating the applied layer to drive off the water.  Up to 50 per cent by weight of the magnesium oxide may be replaced by one or more finely divided, inert, refractory solids consisting of silica metal oxides, metal silicates and metal phosphates such as oxides of aluminium, zirconium and iron, calcium, aluminium and magnesium silicates; and calcium and magnesium phosphates.  The magnesium oxide and the bentonite are initially made up into separate aqueous suspensions which are then mixed.  The bentonite may first be made into a thin slurry with a small amount of ethyl alcohol to facilitate addition to the water. The mixed magnesium oxide - bentonite suspension may be passed through a high speed paint mill.  The suspension may be applied to the sheet material by dipping or by means of a doctor blade or by roller spreading rolls or by electro-phonetic means. The sheet material with the applied layer of suspension is dried in an oven at about 100 DEG C. and may subsequently be annealed at 900 DEG C. to 1300 DEG C.ALSO:A method of providing a thin adherent electrically insulating coating on magnetic sheet material comprises the steps of applying to the sheet a layer, having a thickness of from 25 to 150 per cent of the thickness of the sheet, of an aqueous composition comprising one part by weight of finely divided magnesium oxide, from 2 to 5 per cent of bentonite based on the weight of the magnesium oxide, and from 8 to 16 parts by weight of water and then heating the applied layer to drive off the water.
