Abstract

PURPOSE:To simply obtain isometric antimony oxide having superior oxidation resistance by dropping an aq. antimony chloride soln. on a rotating body to form droplets by scattering, injecting the droplets into water and carrying out hydrolysis. CONSTITUTION:An aq. antimony chloride soln. is dropped on a rotating body such as a disk or cone rotating preferably at about 200-300r.p.m. to form droplets by scattering. The droplets are injected into water at about 60-70 deg.C and hydrolysis is carried out to obtain isometric antimony oxide. This antimony oxide has superior oxidation resistance to oxygen, chlorine, etc., and is suitable for use as a building material, a sealing material for an integrated circuit, etc.

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.

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.

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.

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.
