partikkelointi
Partikkelointi, translated as particleization in several disciplines, is the process of turning a bulk material into discrete particles. The term covers a range of physical and chemical methods that reduce particle size, modify morphology, or isolate particles from a solution or melt. In materials science and chemical engineering, partikkelointi includes milling and grinding (attrition milling, jet milling, ball milling), atomization (gas atomization, spray drying), precipitation and crystallization, and fragmentation during drying or processing. The result is a distribution of particle sizes and shapes, often characterized by metrics such as mean diameter and percentile sizes; agglomeration and aggregation are common challenges.
Applications span pharmaceuticals (where particle size influences dissolution rate and bioavailability), pigments and coatings, catalysts, ceramics,
Measurement and control of particle characteristics rely on several techniques. Particle size distribution is commonly assessed
In practice, partikkelointi aims to tailor particle characteristics to meet performance requirements while managing issues such
