Sebacic acid is prepared by the oxidation of cyclodecanol or cyclodecanone or mixtures thereof, with nitric acid of concentration greater than 60% weight/weight at elevated temperatures in the presence of ammonium vanadate with a trace of copper powder as a catalyst. The cyclodecanol or cyclodecanone or mixture thereof, is added in small portions to the nitric acid solution such that a temperature rise of not more than 5‹ C. is produced, the oxidation of cyclodecanol preferably being effected at about 60‹ C. and that of cyclodecanone at about 80‹ C. When no further exothermic effect is observed, the oxidation may be advantageously completed by heating the reaction mixture for a short period at a higher temperature, e.g. 100‹ C.

An anisotropic permanent magnet is manufactured by orienting particles of an anisotropic mass of powder of a ferromagnetic element or alloy or of ferrite, by subjecting the mass to external magnetic field, isostatically compressing the mass, and slightly deforming it anisotropically and plastically while maintaining isostatic pressure. An alloy powder has hexagonal crystal structure and composition M 5 R wherein M is Co, or a combination of Co with one or more of Fe, Ni, Cu, and R is one or more of elements yttrium, thorium, and rare earths. Alternatively M is Co and R is Sm. The powder is placed in a rubber bag and oriented in a field of at least 1000 Oe., and compressed under magnetization with pressure of 1-2 kilobars, after which the bag is evacuated and sealed for isostatic densification at, e.g., 8k bars. The bag is removed and the block soldered into a ductile, e.g. lead container, which is hydrostatically and isostatically compressed to, e.g. 20k bars, and deformed anisotropically and plastically, during which a saturating field of, e.g., 30,000 Oe. is applied. The container 10 is placed between two perforated loose dies 8, 9 resting on shoulders 2 of the bore of an hydraulic compression vessel 1 containing petrol, and opposed plungers 4, 6 are operated by rams 5, 7. Pressure on container 10 is exerted by plungers 4, 6 until on raising pressure on plunger 6 the liquid column and both plungers descend, until plunger 6 deforms container 10 between dies 8, 9.

After a combustion chamber has been filled with ethylene and oxygen the mixture is detonated by hot combustion gases from a port 22, the chamber then being filled with nitrogen from port 14 the nitrogen acting as a "buffer" to prevent detonation of the ethylene and oxygen as the chamber is again filled. The apparatus may be used to supply combustion gases to a turbine or to a rocket nozzle or for use in coating apparatus as shown in Fig. 3. The apparatus comprises a detonation apparatus 9 as shown in Figs. 1 and 2, nitrogen being supplied to the manifold 24 from ducts 40 and 41. A portion of nitrogen from duct 40 is tapped off through duct 42 and led to a chamber 43 where it picks up coating material contained therein. The nitrogen laden with coating material is fed back to duct 40 and supplied through duct 45 to the ethylene and oxygen manifolds 25 and 26 whereby the coating material is discharged from the combustion chambers together with the combustion gases. The coating material may be tungsten carbide powder which may be used for coating aero engine parts.
