CERAMICS & GLAZES
Zinc oxide is used in specialty ceramic formulations and performance glaze systems where it contributes to controlled melting behavior, fluxing action and structural integrity in ceramic bodies and glazes. Its high purity and controlled chemical composition support consistent firing results, stable glaze appearance and reproducible ceramic performance.
Key Requirements
Controlled Melt Behavior
Zinc oxide influences melting temperature, viscosity and glaze formation during firing, contributing to controlled glaze development and consistent ceramic results.
Surface Quality & Optical Control
High-purity ZnO contributes to improved glaze clarity, brightness and optical appearance while reducing the risk of visual defects during firing.
Thermal Stability During Firing
Ceramic materials are exposed to high firing temperatures where ZnO must remain chemically stable and support consistent glaze and surface formation.
Controlled Impurity Profile
Low trace metal content is essential to prevent discoloration and ensure stable glaze appearance in high-end ceramic products.
Typical Properties
High-purity zinc oxide (typically 97–99.9% ZnO) with controlled trace metal levels and stable particle characteristics supports predictable melting behavior, glaze stability and reproducible firing performance in ceramic applications.
