The melting point of zinc is 419.5°C. At room temperature, it is brittle; at 100-150°C it becomes soft; at over 200°C it becomes brittle. The chemical nature of zinc is active. In Gas at normal temperature, a thin and dense basic zinc carbonate film is formed on the surface to prevent further . When the temperature reaches 225°C, zinc oxidizes violently. Product size: about 1*1mm particles. Shape may not be the same due to cutting tools. Weight: 100g. The granules have uniform particle form and stable chemical characteristics, making them suitable for various professional applications that require consistent material performance. This zinc granule product provides a practical and stable material option for users in related industries and research fields.
