查询词典 etching

A process for making an electronic device which comprises applying a nonaqueous plate-resistant ink by ink jet printing to selected areas of a dielectric substrate, optionally laminated with an electrically conductive metal, exposing the plate resistant ink to actinic and/or particle beam radiation to effect polymerisation, adding one or more metal layers by electrolytic or electroless deposition, the upper layer of which is an etchresistant metal, removing the polymerised plate-resistant ink with alkali and finally removing the electrically conductive metal which are optionally directly laminated to the dielectric substrate and not protected by an upper layer of etch-resistant metal by chemical etching wherein the plate-resistant ink is substantially solvent-free and comprises: A 30 to 90 parts acrylate functional monomers free from acid groups comprising mono- or higher functionality wherein 5 to 95% by weight are mono-functional monomers; B 1 to 30 parts acrylate functional monomer containing one or more acid groups; C 0 to 20 parts polymer or prepolymer; D 0 to 20 parts radical initiator; E 0 to 5 parts colorant; F 0 to 5 parts surfactant; and where the ink has a viscosity of not greater than 30 cPs at 40 DEG C and all parts are by weight.

The α-BaB〓O〓 crystal is colorless, transparent and without cracking. The cracking problem has been overcome by a special growth procedure. The dislocation density, crystallization morphology and growth habit of α-BaB〓O〓 crystal have been systematically studied by chemical etching method, X-ray laue orientation of synchrotron radiation, double-crystal diffraction topography. The growth striation and irregular dislocation consist of the primary defect in α-BaB〓O〓 crystal. The convex solid-liquid interface is stable during the whole growth process.
