High Purity 9999% Zinc Particle Smelting Zinc Particle Small Zinc Block Metal Purification Experiment Zn Zinc Ball Zinc Pellet (Color : 1000g Size : 2 The melting point of zinc is 419.5C. At room temperature, it is brittle; at 100-150C it becomes soft; at over 200C it becomes brittle. The chemical nature of zinc is active. In air at normal temperature, a thin and dense basic zinc carbonate film is formed on the surface to prevent further oxidation. When the temperature reaches 225C, zinc oxidizes violently. Suitable for musical instrument parts and musical instrument casings, coins and other materials. At the same time, zinc itself will not produce sparks with other metals, so it is suitable for underground explosion-proof equipment. Widely used in rubber, paint, enamel, medicine, printing, fiber and other industries. Zinc has suitable chemical properties. Product size: about 2*2mm 3*3mm particles. Shape may not be the same due to cutting tools. Weight: 100g/500g/1000g.
