Zinc Oxide for Ceramic Industry

Enhancing glazes, enamels, and specialty ceramics with high purity Zinc Oxide (up to 99.60%)

Why Zinc Oxide is Essential in Ceramic Manufacturing

Zinc Oxide serves as a multifunctional additive in ceramic production, significantly improving both processing characteristics and final product properties. Our high purity Zinc Oxide is specially processed for optimal performance in ceramic applications.

Key Functions in Ceramic Formulations:

  • Flux Agent: Lowers melting temperature of glazes and enamels
  • Opacity Control: Adjusts translucency in ceramic bodies
  • Thermal Expansion: Modifies coefficient to prevent crazing
  • Color Development: Enhances brightness of colored glazes
  • Surface Quality: Improves smoothness and gloss
  • Crystalline Growth: Promotes development of desired crystal structures

Specialty Ceramics

Ceramic Glazes

Zinc Oxide transforms glaze performance in multiple ways:

  • Matte Effects: Creates satin and matte surfaces at specific concentrations
  • Crystalline Growth: Promotes zinc silicate crystal development
  • Color Response: Enhances brightness of cobalt blues and chrome greens
  • Thermal Expansion: Reduces glaze fit problems
  • Durability: Increases chemical resistance of finished surfaces

Typical addition rate: 5-15% of glaze batch

Zinc Oxide in Ceramic Glazes

Porcelain Enamels

Critical for high-quality enamel formulations:

  • Adhesion: Improves bond to metal substrates
  • Opacity: Controls transparency in cover coats
  • Thermal Shock: Enhances resistance to rapid temperature changes
  • Surface Quality: Produces smooth, defect-free surfaces

Typical addition rate: 3-8% of enamel frit

Zinc Oxide in Porcelain Enamels

Ceramic Tiles

Enhances both production and performance of tiles:

  • Firing Range: Widens acceptable firing temperatures
  • Warpage Control: Reduces tile deformation during firing
  • Glaze Fit: Improves compatibility between body and glaze
  • Color Consistency: Maintains batch-to-batch color matching

Typical addition rate: 2-7% in engobes and glazes

Zinc Oxide in Ceramic Tiles

Specialty Ceramics

Essential for advanced ceramic applications:

  • Electronic Ceramics: Modifies dielectric properties
  • Transparent Ceramics: Aids in sintering of ZnO-based materials
  • Refractories: Improves thermal shock resistance
  • Bioceramics: Provides antimicrobial properties

Addition rates vary by application (1-20%)
