摘要： For producing finely disperse aluminum nitride by reacting hydroxides of aluminum with carbon in a molar ratio of (1:1.5) to (1:2.5), the hydroxides of aluminum are intensively ground together with carbon, in particular carbon black, using a non-aqueous grinding fluid. After the non-aqueous grinding fluid has been separated off from the suspension, the ground material obtained is calcined at 400.degree. to 1000.degree. C., while passing nitrogen through. The material obtained is then treated under intensive contact with nitrogen for 1 to 100 hours at 1400.degree. to 1700.degree. C., before the excess carbon contained in the reaction product is removed by heating to 500.degree. to 900.degree. C. in contact with oxygen-containing gases.The hydroxides of aluminum and the carbon can also be intensively ground separately from one another, using a non-aqueous grinding fluid, and the suspensions obtained can be mixed.

摘要： Phosphorus in vapor form and phosphanes are separated from gas mixtures which consist of carbon monoxide, with or without hydrogen, nitrogen and steam. Concerned are more particularly the off-gases of phosphorus-producing furnaces. To this end, the gas mixture is admixed with at least the stoichiometric amount of oxygen and/or of oxygen-containing gases necessary to achieve conversion of the total phosphorus contained in the gas mixture to oxidation level V. The resulting mixture is introduced into a reaction zone maintained at a temperature within the range 200.degree. to 700.degree. C. and allowed to remain therein over a period of 0.5 to 20 seconds. Resulting phosphorus-V compounds are finally separated from the gas mixture.
