素蒸気の逸散による損失、及びこのガスが装置へ付着し
、運転、保守を困難にする。(Problems to be Solved by the Invention) Since the conventional manufacturing means uses molten iodine, there is loss due to iodine vapor escaping, and this gas adheres to the equipment, making operation and maintenance difficult.
又、切断した破砕品は密度が同一であるから、各用途に
応じたものを一つの装−で製造することができない。Further, since the cut and crushed products have the same density, it is not possible to manufacture products suitable for each use with a single device.

By applying a pressure of Kg/crrt, the molded product can be heated.
この成型品は第１図に示すように温度が高く、圧力が大
きい程密度の大きい成型品を得ることができる。As shown in FIG. 1, the higher the temperature and pressure of this molded product, the higher the density of the molded product.

That is, a lower mold 3 made of Hastelloy having a hole 2 of 20 Iu1ψ is placed on a base made of Hastelloy, and a heating device is provided around the outer periphery of the lower mold 3. Then, a stainless steel piston 7 having a pressurizing part B made of Hastelloy to be inserted into the hole 2 at the tip is inserted into a stainless steel cylinder with a diameter of 50 mm, and this piston 7 is connected to a hydraulic cylinder (not shown). are doing.

Heating at a temperature of 0°C or higher only causes sublimation. Also, add 0 to 00 K9/cri7. 30
If it is less than Kg/cri, it is the same as powdered iodine causing caking, and if it is more than 9/crA to Otsu00, it will simply become dense.
尚、成形時間は数秒で十分に目的を達成することができ
