Target component for cathode sputtering

A target element is formed by creating a precursor system which may yield an inorganic material at a temperature of 300-1600 C. which is lower than the melting point of said material. The precursor system contains an inorganic additive having a melting point no higher than. The precursor system is applied to a support other than a foam or metal felt, the resulting assembly is heated to said temperature and this temperature is maintained for a sufficient time to produce said inorganic material, whereafter the assembly formed by the inorganic material and the support is gradually cooled to room temperature. To produce the target, the target element (2) is bonded to a metal substrate (4) by means of a layer (3) of conductive adhesive.

Process for the preparation of a target component for cathode sputtering

An electrochromic element useful in an electrochromic glass or mirror device and a process for making such element. The element is a five-layered structure including an electrolyte ion conducting layer interposed between first and second inorganic electrochromic layers which are interposed between a pair of conductive electrodes. The first and second inorganic electrochromic layers are different and are capable of exhibiting color-forming properties complementary to one another upon the incorporation of an alkali metal or Ag ion, a mixture of alkali metal or Ag ions or a mixture of alkali metal or Ag and hydrogen ions. The electrolyte ion conducting layer may be a copolymer of ethylene oxide, butylene oxide or methyl glycidyl ether, and optionally a small amount of allyl glycidyl ether, along with an ionizable salt, or may be a polyurethane gel formed by reacting the copolymer with triisocyanate, along with an ionizable salt. The second inorganic electrochromic layer comprises a transition metal oxide which exhibits a color change when shifting between the +2 and +3 valence states. The second inorganic electrochromic layer may be produced by an electrochemical process, a chemical process, or by a physical process. The electrochromic element may also comprise a plurality of five-layer structures in tandem, each pair separated by a substrate.
