Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、溶融塩電解法による三弗化窒素ガス（NF3）
の製造の際に使用される電解槽の改良に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to nitrogen trifluoride gas (NF 3 ) produced by a molten salt electrolysis method.
The present invention relates to improvement of an electrolytic cell used in the manufacture of a metal.

生するガスを隔離するための隔板が設けられている。(Prior art) NH 4 F / HF system using ammonium acid fluoride or ammonium fluoride and hydrogen fluoride as raw materials, and KF obtained by adding potassium acid fluoride or potassium fluoride as the raw material
When the NF 3 gas is produced by the NH 4 F / HF molten salt electrolysis method, the electrolytic cell is provided with a partition plate for separating the gas generated from the anode and the gas generated from the cathode.
上記電解槽においては、陽極からはNF3ガスが、陰極か

れにくい鉄、銅、ニッケルなどの金属板が通常使用され
ている。In the above electrolytic cell, NF 3 gas is generated from the anode and hydrogen gas (H 2 ) is generated from the cathode. These two types of gas, that is, NF 3 gas and H 2 gas, have an extremely high risk of explosion when mixed, so the anode and the cathode are set to prevent mixing of the generated two types of gas in the electrolytic cell. A partition plate is provided for isolation. Further, a metal plate made of iron, copper, nickel or the like which is not easily corroded by the electrolytic bath is usually used for this partition plate.
しかし、この様に電解槽には隔板を設けているにもかか

極化した隔板の陽極と相対する面からH2ガスが発生し、
このH2ガスがNF3ガスと混合し、爆発限界内の混合ガス
を生成するからである。However, even though the electrolytic cell is provided with a partition plate in this way, when NF 3 gas is produced using this electrolytic cell, H 2 gas is mixed in the NF 3 gas generated from the anode to a large extent. Then, gas within the explosion limit may be generated.
This is because the bipolarization phenomenon of the diaphragm occurs during molten salt electrolysis, and H 2 gas is generated from the surface of the bipolarized diaphragm facing the anode,
This H 2 gas mixes with the NF 3 gas to produce a mixed gas within the explosion limit.
そこで、このような爆発限界内の混合ガスの生成を防止
するため、従来は陽極発生ガス中にN2等の不活性ガスを
混入させ、陽極発生ガス中に混入するH2ガスの濃度を低
下させることで爆発の危険を回避する方法が取られて来
た。Therefore, in order to prevent the generation of such mixed gas within the explosion limit, conventionally, by mixing an inert gas such as N 2 into the anode-generated gas, the concentration of H 2 gas mixed in the anode-generated gas is reduced. By doing so, a method has been taken to avoid the danger of explosion.

常一般の技術を適用することは困難である。(Problems to be solved by the invention) However, since this method is not a method of preventing bipolarization of the partition plate, H 2 gas remains mixed in the NF 3 gas, and the fundamental problem is solved. However, there is still a risk of explosion depending on the electrolysis conditions. The use of an insulating material for part or all of the diaphragm is an effective means of inhibiting the electron transfer involving the diaphragm. By the way, aqueous solution electrolysis typified by salt electrolysis is industrially general. In the aqueous solution electrolysis, some insulating materials having durability against the electrolytic solution or the generated gas are known. However, the electrolysis targeted by the present invention, the corrosiveness of the molten salt, the reactivity of the NF 3 gas that is the generated gas is strong, the character of the electrolysis is greatly different from the general electrolysis such as a high operating temperature, It can be said that there is no information on the durability of various insulating materials under the above-mentioned electrolysis conditions, which is the subject of the present invention, and it is usually difficult to apply general techniques.
更に、隔板は、前記の通りその材質が鉄、銅、ニッケル
などの金属板であるので、電解浴に腐蝕されにくいとは
いえ、若干の腐蝕は免れ難いという問題もある。Further, since the partition plate is a metal plate made of iron, copper, nickel or the like as described above, it is difficult to be corroded by the electrolytic bath, but there is a problem that some corrosion is inevitable.

容易ではないと考えられていた。(Means for Solving the Problems) As a method for preventing the bipolarization of the partition plate, a method of eliminating the electrical conductivity of the partition plate is considered, but it is an extremely strong corrosive atmosphere and a high temperature. There is no report on the electrical and electrochemical properties of the diaphragm material under the electrolytic conditions of the method, and it was considered that it is not easy to industrially carry out the prevention of bipolarization by the method.

し、本発明を完成させるに至ったのである。The inventors of the present invention have conducted various studies on prevention of bipolarization of the partition plate, which is a fundamental solution, and as a result, when at least one surface of the partition plate is coated with a fluororesin, the bipolar plate of the partition plate is prevented. Therefore, they have found that the partition plate is not corroded, and have completed the present invention.

An improved electrolytic cell characterized in that it is covered with a system resin coating, and in particular, both surfaces of the partition plate are covered with a fluorine resin coating.
