Properties and Applications

blue-ray red. Dark red powder, soluble in water, but soluble in ethanol red solution, slightly soluble in acetone. In a purple color of sulfuric acid, and it will dilute to product red precipitate; Nitric acid in deep red, turn red after yellow. Its water solution and strong hydrochloric acid red; Add sodium hydroxide fluid shows red orange brown. Dyeing copper ions in slightly dark color. Good levelness. Mainly used in strong acid dye in bath dyeing wool, wool fabrics can be in silk fabric, polyamide fiber and printing. The Barium salt can be used as organic pigment use. Also can be used in the manufacture color amylum, ink and used for leather, paper, soap, wood, electrical-controlled silver, medicine, biology and cosmetics shading.
