Ceramic materials are lightweight, durable, and chemical- and heat-resistant, leading to extensive use in aerospace, construction, medicine, sports equipment and many other industries.

When ceramic components are produced, powdered ceramic material is dispersed in a liquid and then formed into a component shape or green body. This green body is heated to just below the melting point of the ceramic material, the temperature where sintering occurs. It is then that the particles become bonded together, forming an interlocking network which creates a strong mechanical component and, typically, a porous substrate.

Particle size and characterization analysis allows manufacturers in the beauty and cosmetic industry to develop products that meet regulated specifications and reach their standards to achieve a quality product. Knowing the particle size and shape of ingredients determines the quality, properties and performance of their final products

chemical industry


The particles in the composition of materials affect the performance of all manufactured goods. The particle size and characterization of raw materials in coatings, polymers, metals, ceramics and others determine the safety, quality, and properties of a material, such as durability, machinability and sustainability.

For example, plastics can be evaluated for thermal properties such as melting point, glass transition temperature, and decomposition temperature. Understanding when a plastic will melt can aid in the design of a production process or predict failure of a critical part. Determining the particle size of feed material in extrusion equipment ensures a uniform melt during the extrusion process.



Particle Technology Labs is a trusted sub-contractor for manufacturers working as defense contractors. Much like our clients in the pharmaceutical industry, companies that work within the defense industry must be selective in the sub-contractors they partner with.
