Electronic Grade refers to ultra-high-purity chemicals and materials used in semiconductor and microelectronics manufacturing. These substances meet extremely strict purity standards (often 99.999% or higher) to prevent contamination that could damage sensitive components like silicon wafers, integrated circuits, and flat-panel displays. Key applications include wafer cleaning, etching, deposition, and lithography. Impurities—such as metals, particles, and moisture—are controlled at parts-per-billion (ppb) or even parts-per-trillion (ppt) levels. Electronic-grade chemicals (acids, solvents, gases) must comply with industry standards like SEMI and are handled in cleanroom environments to ensure precision and reliability in advanced electronics production.
Zinc Oxide USP is an inorganic white powder composed primarily of ZnO. It is widely used as a functional additive in rubber, ceramics, glass, paints, and chemical industries. Known for its excellent chemical stability, UV-absorbing capability, and reactivity with acids and alkalis, this grade is tailored for industrial applications where high purity is not mandatory but consistent quality and performance are essential.
