FIELD: process engineering.SUBSTANCE: invention relates to powder metallurgy, particularly, to activation of disperse aluminium powder combustion and can be used in various branches of industry. Proposed method comprises impregnation of initial powder with activator based on vanadium oxide compound. Gel is used as said activator containing 4.0-8.2 g/l of vanadium obtained by melting of vanadium oxide or vanadium oxide and lithium or sodium carbonate or vanadium oxide and boric acid or mix thereo...

The invention relates to a linerless label web for labels comprising a face having a first surface and a second surface, and an non tacky adhesive layer arranged on the second surface of the face having a static friction coefficient less than 0.8 against aluminium at room temperature. The invention also relates to use of the label web, to a method for attaching a label to an item, and to a combination of an item and a label. Preferably, the adhesive layer comrises ethylene vinyl acetate (EVA), s...

Disclosed are a type of catalyst which can catalyse the ring-addition reaction of CO2 and an alkylene oxide at 0~180� C. under 0.1~8.0 MPa to produce a corresponding cyclic carbonate and the preparation thereof. The catalyst is a conjugated microporous macromolecule polymer complexed with cobalt chromium zinc copper or aluminium and by using the macromolecule catalysts complexed with different metals to catalyse the reaction of CO2 and alkylene oxide at normal temperature and normal pressure a y...

The present invention relates to a method of manufacturing water resistant aluminum nitride powder the method comprises; in a solvent performing phosphoric acid compound treatment in which at least one phosphoric acid compound selected from the group consisting of phosphoric acid metal salts of phosphoric acid and organic phosphoric acid having an organic group with 12 or less carbon atoms is contacted with aluminum nitride powder dispersed in the solvent so that the ratio of median diameter/pri...
