Abstract: Wet-chemical methods involving the use of water-soluble hydrolytically stable metal-ion chelate precursors and the use of a nonmetal-ion-containing strong base can be used in a coprecipitation procedure for the preparation of ceramic powders. Examples of the precipitants used include tetraalkylammonium hydroxides. A composition-modified barium titanate is one of the ceramic powders that can be produced. Certain metal-ion chelates can be prepared from 2-hydroxypropanoic acid and ammonium hydroxide.

Abstract: An improved magnetic-recording disk and a process for manufacturing magnetic-recording disks are disclosed. An electrically conductive hard coating is deposited upon a ceramic substrate. This coating can be one from the group including the nitrides, carbides, and borides of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, or tungsten. Graded interfacial diffusion or pseudo-diffusion layers are formed between the ceramic substrate and the coating by the elemental metal present in the coating. Magnetic-recording media is then deposited upon the electrically conductive coating. Optionally, a texturable coating that is softer than the hard coating can be placed over the electrically conductive hard coating before the magnetic-recording media is deposited. This texturable coating limits the depth to which abrasive tape texturing can take place.
