Barium Carbonate
Product Overview: Barium Carbonate
Barium Carbonate (BaCO₃) is used as a functional barium compound in ceramic, glass, and specialised industrial systems, providing controlled reactivity and supporting sulphate control, fluxing, and compositional consistency.
In ceramic formulations and structural clay products, it helps manage soluble sulphates and associated surface defects (such as efflorescence and scumming), while in glass and other technical systems it contributes to melt chemistry, refractive index enhancement, and process control.
Key Benefits
Controlled Purity
Supports consistent technical performance across ceramic bodies, glazes, and chemical synthesis.
Sulphate Control
Helps minimise soluble sulphate-related defects by precipitating insoluble barium sulphate, preventing efflorescence.
Good Fluxing Behaviour
Supports firing and melting processes, reducing sintering temperature and enhancing liquid phase sintering.
Consistent Reactivity
Enables predictable formulation response and stable reaction kinetics in high-temperature kilns.
Fine Particle Distribution
Supports uniform mixing, dry blending, and complete dissolution in glass melts and ceramic bodies.
Composition Stability
Provides reliable barium contribution, enhancing glass refractive index, density, and radiation absorption.
