1.Name: Sodium nitrate Chemical formula: NaNO3 Formula weght:84.99 2.Property: (1) ordinary sodium nitrate: white little crystals or light yellow (2) dry powder sodium nitrate: non-caking, showing loose status. Density:2.257. It is liable to deliquesce, dissolved in water, soluble in liquid ammonia, slightly soluble in ethanol and glycerin, Melting Point:308. While being heated up to about 380 it will decompose and release oxygen and turn into sodium nitrite,as the heating goes on, it will decompose into oxygen, nitrogen and nitrogen oxide. It has strong oxidability and can cause combustion explosion if being mixed with organic substance, sulfur, sodium nitrate etc. 3. Usage:Â it has been wildly used in the glass industry, dye, dynamite, metallurgy, machinery, ceramic etc. 4. Specification: (Technical Standards:GB/T4553-2002) Item Unit High G. First G. Qualified G.

We are supplier and exporter of Calcined Alumina. Calcined alumina can be used in the polishing of different alumina products(mainly used in middle, fine polishing).It is also widely used in high-class aluminium refractory material, unshaped refractory materials, high aluminium ceramic product and advanced coating, etc, . Item Al2o3 % Na2o % Sio2 % Fe2o3 % D50 A4m 99.8 0.1 0.05 0.02 3.1 Alumina (Al2O3), the industrial Al2O3 is prepared from alumina (Al2O3, 3H2O) and hard alumina, and the Al2O3, which is high in purity, is usually prepared by chemical methods. Al2O3 has many isomorphic crystals, and there are currently more than 10 known types, mainly three types of crystal, namely gamma-al2o3, beta-al2o3, alpha-al2o3.Which structure is different, with different properties in high temperature above 1300 s almost entirely into alpha Al2O3.
