Product Introduction锛?/strong> 4N alumina is made of white high-purity ultra-fine powder by ultra-fine technology. The product has the characteristics of high activity, non-toxic, odorless, and insoluble in water.The physical properties of high-purity alumina not only directly affect the particles and morphology of the phosphor, but also have a great impact on the optical properties, stability, and light decay of the phosphor. Application characteristics: 1. 4N alumina shows white fluffy powder state, the crystal form is 纬-Al2O3. 4N grade alumina particle size is 20nm; the specific surface area is 鈮?5.55 m2 / gm2 / g. 2. Uniform particle size distribution, high purity, excellent dispersion, high specific surface, high temperature resistant inertness, high activity. 3. Porosity; high hardness, good dimensional stability, excellent dispersion, in solvent water, Solvent ethanol, propanol, propylene glycol, isopropyl alcohol, ethylene glycol monobutyl ether, acetone, methyl ethyl ketone, benzene, xylene, without dispersing agent, stirring and stirring can be fully dispersed.
