325 Mesh Silica Flour

325 Mesh Silica Flour is a finer, high-purity silica flour grade commonly selected for glaze work and other ceramic or industrial applications that prefer smaller particle size and smooth dispersion. In ceramics, it’s often referred to as flint or quartz.

High-Purity 325 Mesh Silica Flour for Ceramic and Fine Industrial Uses

Our 325 Mesh Silica Flour is a high-purity, finely milled silica used where a finer particle size and smooth dispersion are important. It is commonly used in glazes, ceramic formulations, frit systems, and other fine industrial applications where consistency and reliable performance matter.

Available in bulk, palletized 50 lb bags, and FIBC, our 325 Mesh Silica Flour supports both large-scale production and packaged raw-material programs. We work with customers to align product, packaging, and delivery to their process and operating needs.

What to Know About 325 Mesh Silica Flour

Ceramic applications

  • Glazes: Typical mesh used in glaze recipes; silica is the main glass former in many glaze systems.
  • Glaze performance tuning: silica in glazes raises maturing temperature, influences melt behavior/viscosity, and improves durability/craze-resistance.
  • Clay bodies: some bodies specify finer silica for particular behavior; important role in modifying fired properties (shrinkage/porosity/strength) depending on formulation goals.
  • Frit / glaze systems and related ceramic formulations: a finer silica is often preferred where smoothness/dispersion matters.

Industrial manufacturing applications

  • Resin flooring systems: Fine filler for resin flooring and related performance additions.
  • Construction and specialty mixes: grouts and other cementitious/refractory-type formulations that specify fine silica flour.
  • Formulated products: coatings/adhesives, epoxy/plastics, rubber/silicone and other industrial applications where ground silica supports consistency and performance.
  • Specialty glass applications
