Details Introduction

Zinc Sulfide (ZnS) is an inorganic compound that appears as a white to yellow powder at room temperature, insoluble in water but soluble in strong acids. Zinc sulfide has several crystal structure forms, the most common being hexagonal and cubic structures (cubic ZnS is known as sphalerite). Zinc sulfide possesses several important properties:

1. Optical properties: Zinc sulfide has good optical transmission performance, being transparent in the near-infrared to ultraviolet spectrum range, with low absorption of visible light, making it widely used in optical components such as window materials, infrared optical instruments, and night vision devices.

2. Luminescent properties: After doping with specific impurity elements, zinc sulfide can be made into luminescent materials, capable of emitting light under electron beam, X-ray, or ultraviolet irradiation, and is used in fields such as phosphors and luminescent materials.

3. Thermal stability: Zinc sulfide has a certain degree of thermal stability and chemical stability.

4. High resistivity: Pure zinc sulfide is a semiconductor material with a relatively high resistivity.

Application industries:

• Optical industry: Used to make infrared optical lenses, laser window materials, fiber optic connector sleeves, etc.

• Lighting and display technology: Used as a matrix material for phosphors in CRT displays, television screens, and fluorescent conversion layers for LED lights.

• Electronic devices: Used in scintillators for electron microscopes and X-ray detectors.

• Ceramics and friction materials: In the friction materials industry, zinc sulfide can be used as an additive in brake pads and other braking system components to improve friction performance and wear resistance.

• Chemical industry and pigments: Used as a pigment, for example, in the paint and plastics industries.

• Military and aerospace: Used in window and coating materials for night vision devices and radar systems.

Role in brake pads:

Adding zinc sulfide or other sulfur-containing compounds to brake pads is typically done to adjust and optimize the friction coefficient, wear resistance, and thermal stability of the brake pads. Zinc sulfide can help enhance the friction performance of brake pads, particularly maintaining stable friction under high temperatures, thereby improving braking efficiency and safety. Additionally, it can reduce noise generated during braking and help minimize wear on the brake discs. Furthermore, zinc sulfide may synergistically interact with other components to promote the sintering process, enhancing the overall mechanical strength and thermal degradation resistance of the brake pads.
