neodymium nitrate chemical formula Nd(NO3)3 · 6H2O. Molecular weight 438.35. There are two variants of α and β, and the transition temperature is about 22 ℃. Easily soluble in water and ethanol. Vacuum dehydration forms anhydrous salt, and decomposes when strong heat. It is easy to form double salts with other nitrates. For example: 3Mg(NO3)2 · 2Nd (NO3)3 · 24H2O, 3Mn(NO3)2 · 2Nd (NO3)3 · 24H2O, 3Ni (NO3)2 · 2Nd (NO3)3 · 24H2O, etc. Neodymium nitrate solution is an acidic aqueous solution with a purplish red color. Due to the large acidity of the solution, it reacts violently with carbonate raw materials and increases the erosion of refractory materials. Therefore, it is not suitable to directly mix the compound, and must be mixed with sodium carbonate in advance. Neodymium nitrate solution is used as a glass colorant and has no special requirements for the melting of glass. As the amount of introduction increases, it changes from light blue to blue-purple (observed under fluorescent light), and it is blue-purple red in sunlight, also known as rose red. The introduction of a small amount of selenium powder to increase the red tone of the glass, especially at night, can make up for the weakening of the red tone of the neodymium glass, maintain a beautiful purple red, and at the same time reduce the amount of Nd2O3, so as to achieve the purpose of reducing the cost of glass. Experiments show that using neodymium nitrate solution as the raw material of glass colorant is feasible in the process by premixing with soda ash, and the raw material cost is low, with certain economic benefits.
