Physical and Chemical Properties dark blue powder. The relative density was 1.8. Insoluble in water, ethanol and ether, soluble in acid and alkali. The color light can be between dark blue and bright blue, with bright color, strong coloring power, strong diffusion, large oil absorption and slightly poor hiding power. The powder is hard and not easy to grind. It can resist light and dilute acid, but it decomposes when boiled with concentrated sulfuric acid. It is weak in alkali resistance, even dilute alkali can decompose it. It cannot be shared with a basic pigment. When heated to 170~180 °c, the crystal water begins to be lost, and when heated to 200~220 °c, the combustion will release the hydrogen cyanide acid. In addition to a small amount of additional materials that can improve the properties of the pigment, no filler is allowed.
Use cheap dark blue inorganic pigment, a large number of coatings and printing ink and other industrial use, does not produce bleeding phenomenon. In addition to being used alone as a blue pigment, it can be combined with lead chrome yellow to form lead Chrome Green, which is a commonly used green pigment in paint. It can not be used in water-based paint because it is not resistant to alkali. Iron Blue is also used in copy paper. In plastic products, iron blue is not suitable as a colorant for polyvinyl chloride, because iron blue on the degradation of polyvinyl chloride, but suitable for low density polyethylene and high density polyethylene coloring.
