Abstract

Particle size analysis is an experimental procedure that characterizes the particle-size properties of powders using specific instruments and methods. In different application areas, the requirements for powder characteristics vary considerably; among all the parameters used to describe these properties, particle-size distribution is the most widely scrutinized. Below, we will discuss the fundamental concepts and basic techniques of particle-size analysis.

CuCr25–50 Alloy Spherical Powder: Redefining Contact Fabrication


Copper–chromium (CuCr) contact materials exhibit excellent switching performance, superior arc‑erosion resistance, and low current‑limiting characteristics, making them widely used in vacuum circuit breakers and vacuum contactors rated at 126 kV and below. Among these properties, the uniformity of chromium distribution and the degree of grain refinement are critical determinants of the material’s core performance, directly influencing its electrical and thermal conductivity, service life, and dimensional stability. However, conventional powder metallurgy and casting processes have long been constrained by limitations in chromium particle size, resulting in coarse Cr phases, compositional segregation, and elevated oxygen and nitrogen contents. These issues significantly cap the performance ceiling of CuCr materials, posing substantial technical barriers to the production of high‑quality CuCr25–50 alloys.
