    Abstract: 1. A process for manufacturing an electrode consisting of an electrically conducting support structure bearing an electromechanically active boron-containing nickel layer deposited thereon by electroless deposition from a bath of a nickel(II) salt and a complexing agent by reduction with sodium boranate, wherein said bath contains a molar ratio of complexing agent : nickel salt of from 80 to 200, a molar ratio of sodium boranate : nickel salt of from 0.7 to 4.0, from 10 to 400 mmol/l of a hydroxide of sodium, potassium or an alkaline earth metal which is more strongly basic than ammonia, and from 10 to 80 mmol/l of nickel salt.

    Abstract: Pulverulent metal nitrides are prepared in a two-stage process by reacting metal-halogen compounds (metal halides) with ammonia in a first stage and heat treating the reaction products obtained in the first stage at temperatures of from 500 to 1700@C. The metal-halogen compounds are introduced in the form of droplets into a reaction zone having an ammonia atmosphere. The process is particularly suitable for preparing silicon nitride.
