Physical & Chemical properties
Solubility: it is soluble in tartaric acid, sodium sulphide and high-purity sulphuric acid; lightly soluble in alcohol and ammonium salts; Insoluble in acetic acid, low-purity alkali, low-purity inorganic and cool water, it has superior chemical stability.
Sodium pyroantimonate is mainly used as glass clarifier and deformer in color and mono chrome picture tubes, and also in the glass fiber, ruby glass, high-grade glass tableware, etc. And more widely used as the flame-retardant of engineering thermalplastics and rubber, such as flame retardant electronic equipment case, flame retardant carriage, flame retardant wire, also can used as flame retardant of textile, plastics, construction materials, etc.
It is used as flame retardant widely in the world instead of antimony trioxide, confirmed by scientific experiment and production, showing better technical characteristics. Used in all the polymers, it has much better fire resistace, used in saturated polyester and engineering thermoplastics, it has lower resistance to optical and lower tinting strengh, it has the characteristics of low reaction performance, while the common antimony trioxide flame retardant is easy to cause the depolymerization during operation.
