What Is ASTM C1182 Alumina Particle Size Distribution?
ASTM C1182 specifies a standard test method for determining the particle size distribution of alumina powders, typically using sedimentation techniques. The method evaluates how particles settle in a fluid under controlled conditions, allowing accurate measurement of fine particle sizes critical for processing and performance.
This standard is widely used in ceramics, refractories, and advanced materials industries where particle size significantly influences packing density, sintering behavior, and final product quality. ASTM C1182 ensures reliable and repeatable analysis for effective quality control and material optimization.

ASTM C1182 Alumina Particle Size Distribution FAQs
It evaluates the sedimentation of particles in suspension, particularly centrifugal photo-sedimentation, to study the size distribution of alumina powders and similar powders based on them.
The procedure considers particles in the 0.1 to 20 μm range, with a median particle size of 0.5 to 5.0μm.
This helps maintain quality control, product specification, and material research by assuring the accuracy of the particle size measurements.
Particle size distribution affects packing density, sintering behavior, flowability, and final product quality, making it a critical parameter in manufacturing and material performance.
The law of strokes is applied to determine the resistance to movement, the speed at which particles move, and their arrangement during the given manipulations.
