This application provides a composite film for a cable wrapping layer and a preparation method for the same. The composite film for the cable wrapping layer includes a PE film layer, a PET film layer laminated at the PE film layer, an aluminum foil layer laminated at the PET film layer, and a bonding layer arranged between the PET film layer and the aluminum foil layer. The PE film layer is made of raw materials having the following parts by weight: 40-45 parts of LLDPE with a melt index of 0.9-1.1 g/10 min and a density of 0.920-0.922 g/cm.sup.3, 35-40 parts of m-LLDPE with a melt index of 1.9-2.1 g/10 min and a density of 0.917-0.920 g/cm.sup.3 and 15-25 parts of ethylene-vinyl acetate copolymer.

A method for joining quartz pieces using metallic aluminum as the joining element. The aluminum may be placed between two quartz pieces and the assembly may be heated in the range of 500 C to 650 C. The joining atmosphere may be non-oxygenated. A method for the joining of quartz pieces which may include barrier layers on the quartz pieces. The barrier layers may be impervious to aluminum diffusion and may be of a metal oxide or metal nitride. The quartz pieces with the barrier layers may then be joined at temperatures higher than 650 C and less than 1200 C. A device such as an RF antenna or electrode in support of semiconductor processing using joined quartz pieces wherein the aluminum joining layer which has joined the pieces and also functions as antenna electrode.

Gypsum boards formed from synthetic gypsum and other gypsum sources having high chloride salt concentrations. Gypsum boards may include a board core including set gypsum between a front cover sheet and a back cover sheet. A total concentration of the chloride anion in the board core ranges from about 150 to 4000 parts by weight (pbw) chloride, typically about 300 to about 3000 pbw, more typically from about 400 to about 2000 pbw, further typically from about 1000 to about 2000 pbw, and further typically from about 600 to about 1000 pbw, per 1,000,000 pbw calcium sulfate dihydrate. A polymer layer contacts an inner surface of the back cover sheet. A densified gypsum layer contacts an inner surface of the front cover sheet. Methods of making the gypsum board, and a wall system for employing the gypsum boards, are also provided.

A method for bonding infrared transparent materials by placing a polymer comprising at least one chalcogenide element and crosslinking moieties between infrared-transparent optical elements and applying heat, pressure, or both. The crosslinking moieties may be organic, inorganic, or both. Also disclosed is the related bonded assembly comprising infrared transparent optical elements.
