氧化锌是锌的一种氧化物。难溶于水，可溶于酸和强碱。氧化锌是一种常用的化学添加剂，广泛地应用于塑料、硅酸盐制品、合成橡胶、润滑油、油漆涂料、药膏、粘合剂、食品、电池、阻燃剂等产品的制作中。氧化锌的能带隙和激子束缚能较大，透明度高，有优异的常温发光性能，在半导体领域的液晶显示器、薄膜晶体管、发光二极管等产品中均有应用。此外，微颗粒的氧化锌作为一种纳米材料也开始在相关领域发挥作用。
Zinc oxide is an oxide of zinc. Insoluble in water, soluble in acid and strong alkali. Zinc oxide is a common chemical additive, which is widely used in the production of plastics, silicate products, rubber, lubricants, paint coatings, ointments, adhesives, food, batteries, flame retardants and other products. Zinc oxide has large bandgap and exciton binding energy, high transparency and excellent room temperature luminescence performance. It has been applied in liquid crystal displays, thin film transistors, light emitting diodes and other products in the semiconductor field. In addition, as a kind of nano-materials, micro-particles of zinc oxide have begun to play a role in related fields.
氧化锌生产厂家主要集中在辽宁（大连）、山东（潍坊）、河北（高邑、邢台）、江苏、浙江等地，生产的氧化锌以99.7%含量的为主，俗称997（99.7）氧化锌。近年，纳米氧化锌以其优异的纳米特性，增长迅速，应用领域也越来越广泛。
Zinc oxide manufacturers are mainly concentrated in Liaoning (Dalian), Shandong (Weifang), Hebei (Gaoyi, Xingtai), Jiangsu, Zhejiang and other places. The main content of zinc oxide produced is 99.7%, commonly known as 997 (99.7) zinc oxide. In recent years, nano-zinc oxide has been growing rapidly with its excellent nano-characteristics, and its application fields are becoming more and more extensive.
