Optimal Particle Size Range for Feldspar Powder in Ceramic Production: Key Specifications
Optimal Particle Size Range for Feldspar Powder in Ceramic Production: Key Specifications
Feldspar powder is a critical raw material in ceramic production, influencing the final product’s strength, transparency, and thermal stability. Achieving the optimal particle size distribution is essential for maximizing these properties. This article explores the ideal particle size range for feldspar powder in ceramics and highlights advanced grinding solutions to meet industry demands.
Why Particle Size Matters
In ceramic applications, feldspar acts as a flux, lowering the melting temperature during firing. The particle size directly affects:
- Reactivity: Finer particles increase surface area, accelerating vitrification.
- Uniformity: Narrow size distributions prevent defects like pinholes.
- Gloss: Sub-10μm particles enhance surface smoothness.
Ideal Particle Size Specifications
For most ceramic applications, the optimal feldspar powder should have:
| Parameter | Optimal Range |
|---|---|
| D50 | 5-15μm |
| D97 | <45μm |
| +325 mesh residue | <1% |
