3. Borax Pentahydrate for Glazes and Enamels / Ceramics Frits
Borax pentahydrate is a versatile compound that finds extensive use in the formulation of glazes and enamels due to its unique properties. Here are some ways in which borax pentahydrate is utilized in the production of glazes and enamels:
1. Flux Agent: Borax pentahydrate serves as a flux in glazes and enamels, lowering the melting point of the materials and promoting the fusion of different components. This helps in achieving a smooth, glassy surface on ceramics.
2. Color Development: Borax pentahydrate can act as a colorant in glazes and enamels. When combined with other metal oxides, it can influence the color of the final product, allowing for a wide range of hues and shades.
3. Surface Tension: By reducing the surface tension of the glaze or enamel, borax pentahydrate helps in achieving even coverage and consistent application on the surface of ceramics, resulting in a uniform finish.
4. Control of Thermal Expansion: Borax pentahydrate contributes to controlling the thermal expansion properties of glazes and enamels. This is crucial in ensuring that the coating remains stable and does not crack or craze under temperature variations.
Borax pentahydrate plays an important role in ceramic frits
1. Borax pentahydrate can reduce the sintering temperature of ceramic
frits. It can promote the diffusion and rearrangement of mineral
particles, making the sintering process more uniform and efficient.
This helps to reduce energy consumption and production cycles, and
improve product quality.
2. Borax pentahydrate can improve the flowability of ceramic frits. Borax pentahydrate can increase the fluidity of ceramic bodies,
making them easier to shape and shape. It can improve the viscosity
and plasticity of the paste, enhance the stability and efficiency
of the forming process.
3. Borax pentahydrate can improve the mechanical properties of ceramic
frits: Borax pentahydrate can enhance the strength and hardness of
ceramic bodies. It can serve as a binder and reinforcing agent,
increasing the bonding force between ceramic particles and
improving the wear resistance and compressive performance of
finished ceramics.
