(Method for Producing Conductive Tin Oxide Powder)
- the preferred method for producing the conductive tin oxide powder according to the present invention is a method for producing a slurry by adding sodium stannate solution to an acid aqueous solution gradually so that the pH at the end of the addition becomes 5 or less, and reacting the slurry. After washing, filtering and drying, the obtained dried powder is ground, and then fired in a non-oxidizing atmosphere.
- the method of adding the sodium stannate solution to the acid aqueous solution was adopted because the amount of tin in contact with the acid aqueous solution was made small to control the growth rate of the resulting acid tin powder. Is easy to produce, and a large amount of tin oxide particles are not generated at once. This is because it has a particle size distribution.
- the acid aqueous solution referred to in the present invention may be a mixture of one or more of an aqueous solution of sulfuric acid, an aqueous solution of hydrochloric acid, and an aqueous solution of nitric acid capable of causing a neutralization reaction with an aqueous solution of sodium stannate. is there. Among them, it is preferable to use either an aqueous solution of sulfuric acid or an aqueous solution of hydrochloric acid.
- the pH at the end of the addition of the sodium stannate solution to the aqueous acid solution is gradually adjusted to 5 or less, preferably 2 to 4, more preferably 2 to 3.
- a neutralization reaction is carried out by adding calories.
- the reason why the pH is set in the acidic range is that, in the neutral range and the alkali range, the aggregation of powder particles easily occurs. At this time, it is appropriate to add over 5 minutes to 180 minutes. If the addition rate is less than 5 minutes, it is not possible to obtain conductive oxidized tin powder having excellent pulverization characteristics.
- the addition rate exceeds 180 minutes, the productivity is remarkably reduced, and at the same time, the pulverization characteristics of the obtained conductive tin oxide powder are not improved. If the pH at the end of the addition exceeds 5, the resulting conductive tin oxide powder will have poor dispersibility in paint.

OON and the concentration of sodium stannate is lOg / 1-500g / l. It is appropriate to use it. Outside of this range, the effects of process fluctuations such as liquid temperature and pH fluctuations tend to increase.
- the reaction temperature in the neutralization reaction is preferably 30 ° C to 90 ° C. If the neutralization temperature is lower than 30 ° C, the reaction rate is too slow to satisfy industrial productivity. On the other hand, if the neutralization temperature exceeds 90 ° C, the reaction rate becomes too fast and the product quality tends to vary. In addition, if the temperature is not within the range of 30 ° C to 90 ° C, the generated powder particles are excessively agglomerated and cannot maintain good pulverization characteristics. Furthermore, in consideration of the process stability of the neutralization reaction, it is more desirable to employ a neutralization temperature of 50 ° C to 80 ° C in order to minimize variations in product quality.
- the produced slurry is subjected to repulping washing, filtration, and drying. Further, the obtained dried powder is pulverized with a pulverizer.
- non-oxidizing atmosphere examples include a nitrogen atmosphere, a nitrogen atmosphere containing hydrogen, and an argon atmosphere.
- a nitrogen atmosphere containing hydrogen is preferable because it is inexpensive.
- the content of hydrogen is usually 0.1 to 10% by volume, and preferably 13 to 13% by volume.
- the firing temperature is preferably 200 ° C to 1200 ° C, more preferably 300 ° C to 800 ° C, and the firing time is preferably 5 minutes to 120 minutes, more preferably 15 minutes to 60 minutes. It is. It is preferable that the firing conditions be within the above range, since tin oxide, which does not sinter, can easily form oxygen deficiency efficiently. Further, the range provided as more preferable is excellent in the process stability when oxygen vacancies are formed in the silicon oxide tin.
- the conductive tin oxide powder according to the present invention can be added to, for example, paper, plastic, rubber, resin, paint, and the like to impart conductivity thereto. It exhibits excellent dispersibility and transparency of the coating film.
