Abstract:
The invention relates to acicular, ferromagnetic, ferriferous and cobaltiferrous pigments which contain per 100 mol of the molar sum of iron and cobalt, 5 to 20 mol of cobalt, 1 to 5 mol of aluminium, 3 to 10 mol of silicon, 0.7 to 3.5 mol of phosphorus, and oxygen, the sum of the parts by weight of the elements iron, cobalt, aluminium, silicon, phosphorus and oxygen being 95 to 100 % by weight of the total weight of the pigments. The ferromagnetic pigments can also be used to prepare magnetic recording materials.

Abstract:
The invention relates to cosmetic and/or pharmaceutical preparations composed of polymers containing polysiloxanes which are soluble in water or can be dispersed therein, in addition to other polymers and /or filters protecting against ultraviolet light. The invention also relates to the use of such preparations and the use of polymers containing polysiloxanes.
Abstract:
Lithium- and manganese(III/IV)-containing spinels are prepared by reacting stoichiometric amounts of a lithium compound, of a manganese compound and, if required, of a further metal compound at from 200 to 800.degree.C under conditions under which the manganese assumes an average oxidation state of from 3.5 to 4.0, by a process which comprises carrying out the reaction with mixing of the reactants. Spinels which have a novel morphology and can be used as cathode material in electrochemical cells can be obtained.
Abstract:
Lithium and manganese(III/IV)-containing spinels have a specific surface area from 0.1 to 4 m Such spinels can be used as cathode material in electrochemical cells.
