What is an Inorganic Powder? 

Inorganic powders refer to finely divided materials composed of inorganic compounds, which include metal oxides, metals, ceramics, and minerals. These powders are utilised in various applications such as electronics, coatings, catalysts, and advanced materials due to their unique physical and chemical properties. The particle size of inorganic powders can range from larger mesh sizes to low microns and nanoscale dimensions, offering versatility in their usage across different industries.

Particle Size Measurement for Powders

There are three common methods to measure particle size: sieve analysis, Microtrac Laser Diffraction, and Fisher Sub-Sieve Sizing.

Most particle sizes listed in this section are based on Fisher Sub-Sieve Sizing. However, it is important to use the Fisher size as a general guide to powder fineness rather than an exact measure of particle size distribution.

If a particle size is described as -325 mesh, it means the powder will pass through a 325 mesh sieve, indicating that the particles are smaller than 325 mesh. If a powder is labeled as -200, +325 mesh, it means the powder will pass through a 200 mesh sieve but will be retained by a 325 mesh sieve. The size of particles that are smaller than 200 mesh but larger than 325 mesh may vary depending on how they pass through the sieve openings.
