【発明の詳細な説明】
（産業上の利用分野）
本考案は、ダイヤモンドの爆発合成方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for explosively synthesizing diamond.
（従来技術及びその問題点）
爆薬の爆発を利用した従来のダイヤモンドの合成方法に
は、（１）グラファイトに爆発によって加速した物体を
衝突させてグラファイトをダイヤモンドに変換する方法
や、（２）グラファイトを爆薬の爆発で加速し水面等に
衝突させ水中等からダイヤモンド回収する方法、（３）
高性能爆薬とグラファイトの混合物を爆発させてグラフ
ァイトをダイヤモンドに変換する方法等がある。(Prior art and its problems) Conventional methods of synthesizing diamond using the explosion of explosives include (1) converting graphite into diamond by colliding an object accelerated by the explosion with graphite, and (2) converting graphite into diamond. A method of collecting diamonds from water by accelerating it with an explosive explosion and colliding it with the water surface, etc. (3)
Methods include detonating a mixture of high explosives and graphite to convert graphite into diamond.
これらの方法のうち、（１）の方法は原料入り容器に爆
薬で加速した物体を衝突させた後、空中または水中でそ
の容器を拾い、容器内からダイヤモンドを回収する方式
であるが、その物体の加速に必要な装置は１回の爆発加
速で破壊される１回作動かぎりのものであり、またその
ダイヤモンドの原料を入れた容器はこの衝突処理により
二度と使用できなくなる。また使用爆薬量もダイヤモン
ドの原料とするグラファイトの数十倍を必要とする。Among these methods, method (1) is a method in which an object accelerated by explosives collides with a container containing raw materials, and then the container is picked up in the air or underwater and the diamonds are recovered from inside the container. The equipment necessary for the acceleration is a one-time device that will be destroyed by one explosive acceleration, and the container containing the diamond raw material can no longer be used again due to this collision process. Furthermore, the amount of explosive used is several tens of times that of graphite, which is the raw material for diamond.
従って、この方法でダイヤモンドを合成するには多大の
労力と、多量の製造用材料及び爆薬のために費用がかか
る欠点がある。（２）の方法も加速装置の作成に多大な
労力を要し、また１回作動かぎりで破壊してしまうもの
であるので、同様に多大な費用を要する欠点がある。Synthesizing diamond in this way therefore has the disadvantage of being labor intensive and expensive due to the large quantities of manufacturing materials and explosives. Method (2) also requires a great deal of effort to create the accelerator, and the accelerator is destroyed after only one operation, so it similarly has the drawback of requiring a great deal of cost.
（３）の方法には、このような１回作動かぎりの装置は
ないが、その代わりに爆発容器を使い、その由で爆薬と
グラファイトの混合物等を爆発させ、爆発容器の内壁等
に付着した生成物をかき集め、これを精製しダイヤモン
ドを得る方法であるから、爆発容器はその爆発時には密
閉する必要があり、また反応生成物の取り出し等のため
開閉できるようになっている必要がある。そして爆発に
耐え得る強度が必要であり、また爆発時に反応生成物が
燃焼しないように容器内の空気を不活性なガスで置換す
るか、減圧にする必要がある。このように１回の爆発処
理毎に爆発容器の開閉その他の操作を行わねばならない
ので、この方法でも前述の方法と同様に多大な労力を要
しているのが現状である。In method (3), there is no such device that can be activated only once, but instead an explosive container is used to detonate a mixture of explosives and graphite, etc., and the mixture that adheres to the inner wall of the explosive container is removed. Since the method involves collecting the products and refining them to obtain diamonds, the explosion container must be sealed at the time of explosion, and must be able to be opened and closed to take out the reaction products. It must be strong enough to withstand an explosion, and the air in the container must be replaced with an inert gas or the pressure must be reduced to prevent the reaction products from burning in the event of an explosion. As described above, since it is necessary to open and close the explosion container and perform other operations for each explosion treatment, this method currently requires a great deal of labor as well as the above-mentioned method.
（発明の課題）
本発明は、従来技術に見られる前記問題点を解決し、何
度でも容易に所望回数の爆発を繰返し行うことができ、
かつ反応生成物の回収が容易なダイヤモンドの爆発合成
法を提供し、これによりダイヤモンド合成に要する労力
の低減をはかることをその課題とする。(Problems to be solved by the invention) The present invention solves the above-mentioned problems found in the prior art, and allows explosions to be easily repeated as many times as desired.
The object of the present invention is to provide a method for explosive synthesis of diamond in which the reaction products can be easily recovered, thereby reducing the labor required for diamond synthesis.

モンドに変換される。In the present invention, the organic explosive composition itself whose oxygen balance value has been negatively adjusted is used as the raw material for diamond production, and graphite is not mixed therein as in the conventional method. In the present invention, organic explosive compounds and other organic substances contained in the composition are converted into diamond by the high temperature and pressure during explosion.

Explosive compositions in which B is adjusted to a range of -0.25 to -1.2 are also used as preferred explosive compositions in the present invention.
本発明によりダイヤモンドを合成するには、ＯＢが負に

生成物のダイヤモンドが水中外に飛散しないような水深
のところで行う必要があり、これは使用爆薬量や、使用

目安としては５０ｃ＋ｗ以上の水深のところが好ましい
、この爆発処理によりダイヤモンドは水中に生成する。To synthesize diamond according to the present invention, an organic explosive composition in which the OB is negatively adjusted is detonated in water such as an aquarium. The depth at which the composition is detonated must be such that the desired reaction product, diamond, is not scattered outside the water, and this varies depending on the amount of explosives used, the size of the water tank used, etc. However, as a rough guide, it is preferable to use water at a depth of 50c+w or more.Diamonds are formed underwater by this explosive treatment.
ダイヤモンドの密度は水に比し非常に大きいので、水底
に容易に沈殿する。従って、所望回数のその爆発処理を
行った後、上澄液を取り去る方式や水底をさらう方式に
より、ダイヤモンドを含む沈殿物を容易に回収すること
ができる。Diamond has a much higher density than water, so it easily settles to the bottom of the water. Therefore, after performing the explosion treatment a desired number of times, the diamond-containing precipitate can be easily recovered by removing the supernatant liquid or by sweeping the bottom of the water.
また、水中に両端開放または一端開放の管を吊し、その
管内で爆薬組成物を爆発させる方式でもよい。この方式
では、爆発音を減少させることができる上、所望の多数
回の爆発を行うことにより反応生成物は主に管外に沈殿
するようになる。従って、上述の方式により反応生成物

に回収したい時は、一端を封じた管、即ち一端が開口し
た密封管をその長軸がほぼ水平になるように水中に吊り
下げ、その管内で爆発させた後、開口部が上を向くよう
に水中から品り上げる。モして静置後、沈殿物を回収す
る。Alternatively, a method may be used in which a tube with both ends open or one end open is suspended in water and the explosive composition is exploded within the tube. In this method, the explosion noise can be reduced, and by performing a desired number of explosions, the reaction products are mainly precipitated outside the tube. Therefore, the reaction product can be easily recovered by the method described above. In addition, when it is desired to collect the generated reaction products inside a tube, a sealed tube with one end closed, that is, a sealed tube with one end open, is suspended in water so that its long axis is almost horizontal, and an explosion is caused inside the tube. Then lift it out of the water with the opening facing upwards. After stirring and allowing to stand still, collect the precipitate.
このようにして得られる反応生成物中には金属類やグラ

硝酸の混合液で処理することにより純度の高いダイヤモ
ンドが得られる。Since the reaction product obtained in this way contains by-products such as metals and graphite, the metals are first dissolved and removed from the reaction product with nitric acid, as in the case of normal diamond synthesis methods. A highly pure diamond can be obtained by treating with a mixture of chloric acid and nitric acid until all graphite is removed, and finally with a mixture of hydrofluoric acid and nitric acid.

ィン等を用いるのが好ましい。According to the invention, the explosive composition is advantageously used as a shaped article. In this case, it is preferable that the density of the molded product is 6≦i, and the stirrup is preferably high-density, and it is usually advantageous to press-mold the molded product to a density of 1.4 g/- or more. Although its shape is not particularly limited, it is usually used as a cylindrical molded body. Further, it is preferable to use paraffin or the like as a molding aid in this molded product.

場合、水槽の底部の形状は、反応生成物が沈降しやすく

るのが有利である。In the present invention, the explosive composition is detonated in water,
In this case, the size and strength of the water tank used should be designed so that it will not be destroyed by the explosion. Further, when using a water tank, it is advantageous that the bottom of the water tank has an inverted conical shape so that the reaction products can easily settle and can be easily recovered to the outside.
