Praxair and Advance Research Chemicals Form Alliance to Manufacture Tungsten Hexafluoride.Business Editors DANBURY, Conn.--(BUSINESS WIRE)--Nov. 2, 2000 Praxair, Inc. (NYSE NYSE See: New York Stock Exchange : PX) and Advance Research Chemicals (ARC) announced today that they have formed a strategic alliance to develop, manufacture and market tungsten hexafluoride (WF6) for the semiconductor industry. ARC will exclusively manufacture a high purity WF6 for Praxair to market and distribute to semiconductor manufacturers worldwide. The new plant, located in Catoosa, Oklahoma, a suburb of Tulsa, is currently capable of producing approximately 10,000 kg annually and has the capability of expanding to over 40,000 kg per year. The alliance utilizes ARC's fluorine fluorine (fl  `ərēn, –rĭn), gaseous chemical element; symbol F; at. no. 9; at. wt. 18.998403; m.p. −219.6°C;; b.p. −188.14°C;; density 1. production expertise and enhances Praxair's position as a full line supplier to semiconductor manufacturers by providing a consistent source of high purity WF6. "I believe that the purity of the WF6 being produced at the Catoosa facility is one of the highest in the industry," states Dr. Dayal T. Meshri, President/CEO. Industry demands for fluorine molecules have risen sharply because several other fluorinated fluorinatedmaterial to which a fluoride has been added, e.g. water for human consumption treated as a prophylaxis against tooth decay. gases are limited in capacity. Tungsten hexafluoride is used by semiconductor chip manufacturers in the low pressure and plasma enhanced chemical vapor deposition (CVD CVD Cardiovascular disease, see there ) of tungsten and tungsten silicides ARC is the largest producer of lithium electrolyte salts in the US and is the only US producer of CFx (Polycarbon monofluoride), which is used as a cathode material, lubricant, image producing filler, and gas separation. ARC's technology involves fluorination fluor·i·na·tion n. A chemical reaction that introduces fluorine into a compound. with anhydrous an·hy·drous adj. Without water, especially water of crystallization. anhydrous (anhī´drus), adj without water. anhydrous containing no water. HF, aqueous HF, elemental fluorine, interhalogens, and fluorinating reagents. ARC, a privately held company privately held company A firm whose shares are held within a relatively small circle of owners and are not traded publicly. , is led by Dr. Meshri, President/CEO. ARC caters the needs of automobile, photo initiator, metal finishing, pharmaceutical, plastics, performance additives, electronic, semiconductor, optics, high energy battery systems, and research institutes.
