99.99% Ultra-high Purity Zinc Oxide（4N Zinc Oxide）

Shandong Huiyuan Zinc Products Factory produces high-purity indirect-process zinc oxide by adopting a series of measures, including selecting premium-grade 0# metallic zinc ingots, optimizing the production process, and strictly controlling every step of the manufacturing procedure to ensure that the product’s purity remains consistently above 99.9%. High-quality products can achieve purities of 99.99% or even higher—exceeding 99.999%. Due to its exceptionally high purity (with a main content of 99.9% or more) and extremely low levels of impurities—such as trace amounts of heavy metals like lead, cadmium, and arsenic—it is primarily used in high-end fields that have extremely stringent requirements for material purity, including advanced fine chemicals and new materials, pharmaceuticals, food processing, and optical glass manufacturing.
