| Physical and Chemical Properties | alumina White is a general term for a contraceptive-permeable white pigment composed of an aluminum compound, without a fixed chemical composition. In general, aluminum hydroxide [Al(OH)3], aluminum oxide hydrate (Al2O3 · H2O), or water-insoluble basic aluminum sulfate [Al2(SO4)(OH)4], etc. It has also been reported that it is composed of a water-insoluble tetrabasic aluminum sulfate and aluminum dihydroxide polymer [Al2(SO4)(OH)4 · Δh2o · 2Al(OH)3]n. The refractive index ranges from 1.47 to 1.56. Mixed with linseed oil was transparent. |
| Use | as a filler for a high-quality Lake for the preparation of a transparent ink. It is also used as a pigment for printing inks, coatings (fillers and thickeners), and rubber (fillers). It is also used as a surface treatment agent for leather and paper. Also used for painting pigments, crayons |
alumina White is a general term for transparent white pigments composed of aluminum compounds. There is no fixed chemical composition. Generally refers to aluminum hydroxide [Al(OH)3], aluminum oxide hydrate (AI203.xH20) or water insoluble basic aluminum sulfate [AI2 (S04) (OH)4], etc, it has also been reported to be made from water-insoluble tetrabasic aluminum sulfate, aluminum dihydroxide polymers [AI2 (S04) (OH)4 .. XH20 · 2AI(OH)3]. Composed. The refractive index ranged from 1. 47 to 1. 56. Mixed with linseed oil was transparent.
in the aluminum sulfate solution, an alkali solution is added under stirring to form a precipitate, which is washed, filtered, dried at low temperature, and then pulverized to obtain a finished product. The dehydrated paste can also be used directly as a product. The concentration, temperature, reaction temperature and drying temperature of each solution affect the quality of the product.
