Abstract: PURPOSE:To produce Na hydrocarbon dispersion of high quality by dispersing a melt of industrial Na contg. Ca in hydrocarbon and cooling the same in an inert gaseous atmosphere in the presence of Na oxide and molecular oxygen. CONSTITUTION:Industrial Na contg. Ca which is an impurity is heated and melted in an Na melting tank 1, after which it is charged at 45-60% ratios into a mixing tank 2 contg. arom. hydrocarbon such as toluene, where these are stirred vigorously, and a dispersion assistant such as oleic acid is added at 1-5% ratios to these from a tank 3. Air or Na oxide such as Na2O is added under stirring at 100-1000ppm ratios expressed in terms of O2, and at the point of the time when the dispersion of Na ends, hydrocarbon such as benzene is charged into a quick cooling tank 4, whereby the mixture is quickly cooled.

Title: Magneto-optical recording medium and production thereof
Inventor: KASHIWATANI MAKOTO
IPC: C23C14/14
Filed: 1990-04-02
Abstract: PURPOSE:To decrease the fluctuations in bias characteristic and EWR characteristic by specifying the film forming conditions for a dielectric protective layer. CONSTITUTION:The reason why gaseous hydrogen significantly affects the bias characteristic and EWR characteristic is estimated to lie in that the chemical activity on the metal to constitute a recording layer is high or the influence to be exerted on the film structure of the dielectric protective layer is significant. The dielectric material is, thereupon, sputtered on a transparent substrate by impressing an electric power to a dielectric target while maintaining the residual amt. of the gaseous hydrogen in a low-pressure inert gaseous atmosphere at <=1,000ppm of the inert gas, by which the dielectric thin film is formed on the transparent substrate. The bias characteristic and EWR characteristic of the resulted magneto-optical recording medium are improved to decrease the fluctuations.
