Description
【発明の詳細な説明】 本発明はＸＳ＠折装置の試料高温装置の改良に関する。[Detailed description of the invention] The present invention relates to an improvement of a sample high temperature device for an XS @ folding device.

とにより、熱電対の１ｌＦＩＩを防止することにある。The purpose of this Ijio is to use a semiconductor thermocouple with tungsten for the middle leg and graphite (hereinafter referred to as W-Gr) as the material for the thermocouple O for controlling the 11 degrees of the sample high temperature device. The purpose is to prevent it.

にはこの部分から断線して使用できなくなるという不具
合が発生していた。The material of the thermocouple for controlling the temperature of conventional sample high temperature equipment is 87% platinum and 13% platinum alloy for the middle leg, and 100% platinum (hereinafter referred to as Pt/13Rh-1t) for the - leg.
A noble metal thermocouple was used. Conventional products made of Pt and filth-Pt can be used to analyze ordinary samples at high temperatures, but rare earth Fpart magnets such as sumariram cobalt magnets (hereinafter referred to as am-oo magnets and moving magnets) When performing X@ diffraction analysis under high temperature conditions,
Since the O-containing element of the 1si-Go magnet is a metal that easily evaporates at high temperatures, theory B and the Pt of the thermocouple react with each other to form a compound called gjmlPt. Therefore, IIs, Pt compound is one leg of thermocouple O
This compound acts on the Pt wire and gradually grows and expands under high temperatures, causing the growing part to become brittle and brittle, eventually causing the wire to break and become unusable.
本発明はかかる欠点をＷｋｍしたもので、熱電対として
ｐｔ−ｔａｎｋ−ｙｐ＊＠に代わるＷ −Ｇ ｒ線を使
用し熱電対の断線を防止したものである。The present invention solves this drawback by using a W-Gr wire instead of pt-tank-yp*@ as a thermocouple to prevent disconnection of the thermocouple.
ＷおよびＧ’ｒは希土類元素とは金属間化合物なつくら
ず、またｍｓもし合わない。したがって希土類元素の代
表的元素であるｓｍとも反応しないため、熱電対Ｏ長寿
命化が計れるものである。W and G'r do not form an intermetallic compound with rare earth elements, and neither do they have ms. Therefore, since it does not react with sm, which is a typical rare earth element, the life of the thermocouple O can be extended.
以下、実施例をあげ本発明の詳細な説明する。Hereinafter, the present invention will be described in detail with reference to Examples.
実施例は次の試験方法により行なった。Examples were conducted using the following test method.
（ｉ）線１１ （Ｌ 、Ｓ ＩＩｍの本発明品を試料高
温装置のデ体に取りつける。(i) Attach the inventive product of wire 11 (L, S IIm) to the body of the sample high temperature device.
Ｃ）室温から１５００℃まで昇温し、その温度で１時間
保持したのち自然放冷により降温する。C) The temperature is raised from room temperature to 1500°C, held at that temperature for 1 hour, and then lowered by natural cooling.
（８）試料はａｉｍ−００系磁石パウダーを使用し、１
回Ｏ昇温→降温のつど、新しいパウダーに散り替える。(8) The sample used aim-00 series magnet powder, 1
Every time the temperature rises and falls, sprinkle with new powder.
（４）試料および熱電対の高温醸化防止のため、不活性
ガスであるアルゴンガスを２６４流す。(4) In order to prevent the sample and thermocouple from accumulating at high temperatures, argon gas, which is an inert gas, is flowed at 264°C.
上記試験方法により、熱電対が断線するまでＯ繰り返し
回数によって評価した結果、従来品の２１・１５！Ｌｈ
−Ｐｔ線は２０回の繰り返し回数にようて一脚のｐｔｌ
ｌが断線してしまったが、本発明によるＷ −Ｇ ｒ線
は３０回繰り返してもなお充分に使用可能である。According to the above test method, the thermocouple was evaluated by the number of O repetitions until it broke, and the result was 21.15 compared to the conventional product! Lh
- The Pt line is the monopod's ptl as per 20 repetitions.
1 was broken, but the W-G r wire according to the present invention can still be used satisfactorily even after 30 repetitions.
以上より、本発明１は従来品に比べて、断線に対してき
わめて強いことがわかる。From the above, it can be seen that the present invention 1 is extremely resistant to wire breakage compared to conventional products.
したがって高温下における希土類元素のＸｉｌ＠折に応
用した場合、充分な効果が得られるものである。Therefore, when applied to Xil@-folding of rare earth elements at high temperatures, sufficient effects can be obtained.
