本発明は耐酸化性が高い等軸品構造を有するアンチモン
（Ｓｂｚ（Ｌ＋）の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for producing antimony (Sbz(L+)) having an equiaxed structure with high oxidation resistance.

ていた。この方法で得られた５ｂ２０３は柱状晶であり
、酸素や塩素等に対する耐酸化性が必ずしも高くなく、
難燃剤としての効果が不十分であるという問題点を有し
ていた。5bz03 is widely used as a flame retardant in building materials and encapsulating materials for integrated circuits. Conventionally, crude 5bzO obtained in a converter
s was dissolved in hydrochloric acid to form an aqueous antimony oxide solution of about 1000 to 1500 g/A, and this aqueous solution was poured into high-temperature water to carry out a hydrolysis reaction to produce 5bzO3. 5b203 obtained by this method is a columnar crystal and does not necessarily have high oxidation resistance against oxygen, chlorine, etc.
The problem was that the effect as a flame retardant was insufficient.
本発明の目的は従来技術の上記問題点を解消するために
、耐酸化性が高い等軸品の５ｂ２０３を得る方法を提供
することにある。An object of the present invention is to provide a method for obtaining equiaxed 5b203 having high oxidation resistance in order to solve the above-mentioned problems of the prior art.

、該液滴を前記水中へ注入添加する点に特徴がある。In order to solve the above problems, the method of the present invention is a method for producing antimony oxide by injecting and adding an antimony chloride aqueous solution into water to perform a hydrolysis reaction, in which the antimony chloride aqueous solution is dropped onto a rotating body and scattered. The method is characterized in that the droplets are formed into droplets and the droplets are injected into the water.

５ｂ２０：＋が得られる。The concentration of the antimony chloride aqueous solution is 100, which is commonly used.
0 to 1500g/A is good. A typical example of the rotating body is a disk. In the case of a disk, its diameter is not particularly limited, but it is preferably about 30 to 3001 m, and the rotation speed of the disk is such that the dropping antimony chloride aqueous solution is scattered by the centrifugal force of the rotating disk and becomes droplets. However, it varies depending on the desired diameter range of the disc, and is about 100 to
500 rpm is desirable. Another example of a rotating body is a downwardly expanding cone, which provides a more favorable effect than the disk. In the case of the cone, the base diameter is 50
~150 m long, height 5 ~], OO1 m is desirable, and the rotation speed is preferably 200 to 300 rpm. Also,
The temperature of the water used in the method of the present invention is preferably 50 to 95°C;
60-70°C is preferred, less than 50°C or 95°
If it exceeds C, it becomes difficult to obtain equiaxed 5bzOa, which is not good. According to the inventor's confirmation, the droplets scattered from the rotating body as described above are finely divided into equiaxed crystals of 5b2o3 as soon as they are added to water. Incidentally, if stirring is performed during the hydrolysis reaction, 5b20:+ having a more uniform particle size can be obtained.

0 ml was dropped onto the top of a polyethylene cone with a bottom diameter of 90 mm and a height of 70 mm at a rate of 60 mβ/min. The rotation speed of the cone was maintained at 200 to 300 rpm, and the scattered droplets of the aqueous anddimon chloride solution were added to water maintained at 60°C to perform a hydrolysis reaction.
尚、上記水中へ攪拌子を入れて２００〜３００ｒｐｍの
攪拌を行った。このようにして、得られた５ｂ２０３を
観察したところ粒径が１９〜１５μｍであり、等軸晶の
結晶構造を有していた。A stirrer was placed in the water and stirred at 200 to 300 rpm. When the 5b203 thus obtained was observed, it was found to have a particle size of 19 to 15 μm and an equiaxed crystal structure.
本発明方法を行うことにより、簡便に耐酸化性が高い等
軸晶の５ｂ２０３を得ることができる。By carrying out the method of the present invention, equiaxed 5b203 having high oxidation resistance can be easily obtained.
