Abstract:
A diamond-containing material having the following element content ratio in per cent by weight: carbon 75-90, hydrogen 0.6-1.5, nitrogen 1.0-4.5, oxygen the balance, the following phase content ratio in per cent by weight: roentgen amorphous diamond-like phase 10-30, diamond of cubic modification the balance, and having a porous structure. 10-20 % of the surface of the material consists of methyl, nitryl and hydroxyl groups of two types, as well as functional oxycarbonic groups of the general formula O=R where R represents =COH, =COOH, =CO, =C₆H₄O or any of their combinations, and 1-2 % of the surface consists of carbon atoms with non-compensated links. A method for obtaining said material consists in detonation of a carbon-containing explosive substance with negative oxygen balance, or a mixture of explosive substances, in a closed volume in the atmosphere of gases inert to carbon, with an oxygen content of 0.1-6.0 % by volume, at a temperature of 303-363 K and in the presence of ultradispersed carbon phase with concentration of 0.01-0.15 kg/m.
Abstract:
A process for producing ultra-fine ceramic particles with the particle size of less than 1000 A, which comprises the steps of forming powdered dust cloud of metal powder such as Si constituting a portion of aimed ceramic particles in a reaction gas containing the other portion of said aimed ceramic particles, igniting said powdered dust cloud to cause explosive burning and synthesizing said aimed ceramic particles and gathering said resulting ceramic particles. By the process, ceramics particles such as Al 2 O 3 , MgO, SiO 2 , TiO 2 , TiN having particle size of 10 - 100 nm can be produced.
Abstract:
A thermal insulation system for a window comprising a roller blind (22) carried by a roller blind mechanism which is arranged to be fixed to a window frame (14) above a window (18) to be insulated. The blind (22) is adapted to be detachably connectable to the window frame (14) by means of touch fastener (Velcro) strips (24a, 24b, 26) carried by the longitudinal side edges and the free transverse edge of the blind (22) and mating touch fastener strips (28a, 28b, 30) carried by the frame. A mounting mechanism (48, 50) for the roller blind should enable this to be selectably displaceable between a first position, in which the roller blind mechanism is spaced from the frame (14) to enable the blind (22) to be retracted and extended against the tension of a rewind spring within the mechanism, and a second position in which the roller blind periphery engages a resilient strip (60) disposed across the window frame above the window to provide sealing at the upper end of the blind.
