摘要:Polymeric Precursors For Carbothermal Reactions Were Prepared From The Chelate Derivatives Of Titanium And Zirconium Alkoxides L2M(Or)(2) (L Is An Acetylacetonato Or Ethyl Acetoacetato Group) In Alcohols By Reaction With Organic Compounds Having Two Or More Reactive Oh Groups,Such As Ethylene Glycol,Saccharose,Tartaric Acid Or Dihydroxybenzenes. These Organic Groups Act As Bridging Ligands In Transesterification And Condensation Polymerization Yielding Either Spinnable Viscous Solutions Or Elastic Gels. The Rheological Properties Of The Concentrated Solutions Allowed For The Preparation Of Polymer Fibres And Films. At Temperatures Up To 1600 Degrees C,Bulk Precursors As Well As Fibres And Films Were Thermally Converted Into Carbide Powders,Films Or Coatings. The Structural Transformations Of The Polymeric Materials Into The Carbides Were Investigated Using Thermogravimetric-Differentia I Thermal Ana Lyses (Tga-Dta),X-Ray Diffraction (Xrd),Scanning Electron Microscopy (Sem),Fourier Transform Infra-Red (Ftir) Analysis And Raman Spectroscopy.

标 题:Synthesis of transition metal carbonitrides

摘要:Transition metal carbonitrides (in particular, titanium carbonitride, TiC 0 .5 N 0 .5) are synthesized by a self-propagating reaction between the metal (e.g., titanium) and carbon in a nitrogen atmosphere. Complete conversion to the carbonitride phase is achieved with the addition of TiN as diluent and with a nitrogen pressure ≧0.6 MPa. Thermodynamic phase-stability calculations and experimental characterizations of quenched samples provided revealed that the mechanism of formation of the carbonitride is a two-step process. The first step involves the formation of the nonstoichiometric carbide, TiC 0 .5, and is followed by the formation of the product by the incorporation of nitrogen in the defect-structure carbide.

摘要:A process for the production of epoxides of the formula (I): (I) in which the benzene ring A is substituted with 1 to 3 halogen atoms, which are the same or different, and optionally carries other substituents, and R1 is which is the same as or different from the other group or C1-6 alkyl, the process comprising electrolyzing the corresponding alkene of the formula (II): (II) in a medium comprising a solvent for the alkene and an aqueous solution of a halogen salt, the solvent/water ratio by weight being greater than unity, the solvent being miscible with water at the solvent/water ratio used and being chemically inert to both the alkene and the free halogen produced from the halogen salt by the electrolysis. The epoxides are useful in the synthesis of fungicidal compounds and certain of the epoxides are novel compounds.

摘要:A method and apparatus for the production of high density, monolithic cerc materials. A mixed powder such as Titanium-Carbon is first subjected to uniaxial pressure to form a green compact. The compact is positioned in a vented mould between two steel plates, reacted by a combustion synthesis process called SHS and then subjected to an explosively generated shockwave by an explosive charge positioned on the upper steel plate, which generates high pressures to compress the hot, porous ceramic to form high purity ceramic of more than 90% theoretical densities.
