Products Description
Oxide zinc, typically presenting as a white powder or hexagonal crystal, is notable for its thermal behavior: it turns yellow upon heating but reverts to white upon cooling, and sublimates at 1800℃. As an amphoteric oxide, it reacts readily with both acids and bases, and while it is insoluble in water, it dissolves in acidic and basic solutions. With a high refractive index and semiconductor characteristics, zinc oxide is valued for its thermal stability and versatile applications. It serves as a key material in various industries-a white pigment in coatings, an antibacterial and sunscreen component in medicine and cosmetics, and a semiconductor in electronics. Additionally, its nano form boasts remarkable photocatalytic and antibacterial capabilities, making it highly useful in environmental and biomedical applications.

Applications
Zinc oxide serves as a vital additive in multiple industries. Within the rubber sector, it functions as a strengthening and activating agent, enhancing the durability and elasticity of rubber products. As a pigment, it imparts a white hue to various materials and is integral to the vulcanization process, improving rubber's resistance to wear and tear. Additionally, it acts as a catalyst and desulfurization agent, particularly in the fertilizer industry, where it helps remove sulfur-containing impurities from gases.
In chemical engineering, zinc oxide is employed for desulfurization processes and serves as a reagent and a base material for other compounds. In electrostatic applications, it plays a crucial role in photocopying, transfer printing, and recording technologies, contributing to the clarity and longevity of printed materials.
For the plastics and cosmetics industries, zinc oxide is a versatile component. It is used in the formulation of various products, including sunscreens, where it provides UV protection. It also finds application in ceramics, coatings, and textile processing, enhancing the quality and functionality of these materials.
In industrial gas processing, zinc oxide is utilized in the production of ammonia, methanol, and hydrogen, as well as in the purification of petroleum and water. Its ability to remove impurities makes it an essential component in maintaining the efficiency and safety of these processes.
Medically, zinc oxide is valued for its astringent properties, commonly used in ointments and rubber-based medical products to promote healing and prevent infection. It also serves as a white pigment in printing inks, paper, and match production, providing a bright, opaque finish.
Beyond these applications, zinc oxide is a precursor for manufacturing various zinc compounds. It is also used in the production of electronic laser materials, phosphors, feed additives, catalysts, and magnetic materials, showcasing its diverse utility across different scientific and industrial fields. Overall, zinc oxide is a highly versatile material with a broad spectrum of applications that span multiple sectors.
