A separator of the present invention for a nonaqueous electrolyte secondary battery is obtained by fluorinating a polyolefin based resin. A contact angle of the separator with a nonaqueous solvent electrolyte is 40° or less a shutdown temperature of the separator is 170°C or less. Further, a multilayered separator of the present invention for a nonaqueous electrolyte secondary battery includes a plurality of layers, at least one of which is the foregoing separator for a nonaqueous electrolyte secondary battery. These separators for nonaqueous electrolyte secondary battery have both a favorable electrolyte-retaining characteristic and a suitable shutdown performance.

Achieved is a ceramic carbon composite material and a ceramic-coated ceramic carbon composite material which are lighter than ceramics and excellent in at least one of properties including oxidation resistance, resistance to dust generation, heat conductivity, electrical conductivity, strength, and denseness. The ceramic carbon composite material is a ceramic carbon composite material in which an interfacial layer of a ceramic is formed between carbon particles of or containing graphite. The ceramic carbon composite material can be produced by forming a green body from ceramic-coated powder in which the surfaces of carbon particles of or containing graphite are coated with individual ceramic layers and sintering the green body.

This invention provides an electrolytic apparatus for producing fluorine or nitrogen trifluoride by electrolyzing a molten salt containing hydrogen fluoride, which electrolytic apparatus does not cause any anode effect even at high current density and can be operated without anodic dissolution. The electrolytic apparatus is an apparatus for producing fluorine or nitrogen trifluoride by electrolyzing a hydrogen fluoride-containing molten salt at an applied current density of 1 to 1,000 A/dm2 and is characterized in that an electrode covered with an electroconductive diamond is used as an anode.
摘要:
Fluorine gas generators are connected with semiconductor manufacturing apparatuses 3a to 3e through a gas supplying system 2 including a storage tank 12 that can store a predetermined quantity of fluorine gas generated in the on-site fluorine gas generators 1a to 1e. When one or more of the on-site fluorine gas generators 1a to 1e are stopped, fluorine gas is supplied to the semiconductor manufacturing apparatuses 3a to 3e from the storage tank 12 storing a predetermined quantity of fluorine gas, so as to keep the operations of the semiconductor manufacturing apparatuses 3a to 3e. Thereby obtained is a semiconductor manufacturing plant in which fluorine gas generated in the fluorine gas generators can be safely and stably supplied to the semiconductor manufacturing apparatuses, and the cost performance is superior.
