YINETTECH 5pcs 99.9% Pure Zinc Zn Sheet Plate 100x100x0.2mm Science Lab

Product Overview

This listing is for 5 pieces of high-purity 99.9% pure zinc (Zn) sheet plates, each measuring 100x100x0.2mm. These zinc sheets are suitable for various science lab applications and industrial uses.

Properties of Zinc

Zinc is a bluish-white metal with a density of 7.14 g/cc and a melting point of 419.5 °C. It is brittle at room temperature, softens between 100-150 °C, and becomes brittle again above 200 °C.

Chemically, zinc is active. In air at room temperature, it forms a thin, dense basic zinc carbonate film that prevents further oxidation. Intense oxidation occurs at 225 °C, and it burns with a blue-green flame.

Applications

• Materials for instrument parts and instrument shells
• Coin production
• Underground explosion-proof equipment (does not cause sparks with other metals)
• Widely used in rubber, paint, enamel, medicine, printing, and fiber industries
