YINETTECH 5pcs 99.9% Pure Zinc Zn Sheet Plate Foil 140x140x0.2mm Science Lab

Product Overview

This listing is for a set of 5 YINETTECH high purity 99.9% pure Zinc (Zn) sheet plates. Each plate measures 140x140mm with a thickness of 0.2mm, making them suitable for various science lab applications.

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. At room temperature, it is brittle; it softens between 100-150 °C and becomes brittle again above 200 °C.

Zinc exhibits active chemical properties. In room temperature air, a thin, dense basic zinc carbonate film forms on the surface, preventing further oxidation. Oxidation intensifies at 225°C, and it burns with a blue-green flame.

Applications

• Materials for instrument parts and instrument shells.
• Component in coin production.
• Suitable for underground explosion-proof equipment due to its non-sparking nature when in contact with other metals.
• Widely used in rubber, paint, enamel, medicine, printing, and fiber industries.
