Chemical Total Element Analysis (ICP-MS) is a widely used instrument technology in the field of chemical analysis. It is developed based on inductively coupled plasma mass spectrometry (ICP) technology.

When it comes to powdered materials, density is an essential parameter that determines their physical and chemical properties. Different methods are employed to measure powder density, including loose bulk density, tapped density, true density, apparent density, bulk density, and compacted density. This article will discuss these parameters, and how they affect the properties of powdered materials.

Particle rearrangement and densification: In liquid-phase sintering, the generation of liquid phase and particle rearrangement are key steps in densification. Small particles have a large specific surface area and surface energy. After the liquid phase is generated, the solid phase is wetted by the liquid phase and infiltrates into the gaps between particles. If the amount of liquid phase is sufficient, the solid phase particles will be completely surrounded by the liquid phase and approximate a suspended state. Under the surface tension of the liquid phase, they will undergo displacement and adjustment of position, thus achieving the most compact arrangement. At this stage, the density of the sintered body increases rapidly

The 16th China International Powder Metallurgy & Hard Alloy Exhibition, also known as PM CHINA, is the flagship event of the global powder metallurgy industry. Since its establishment in 2008, it has grown at an astonishing rate of 30% annually, from a few hundred square meters to a massive 40,000 square meters in 2023. With its extensive international reputation and global influence, PM CHINA has become a must-attend event for companies worldwide.

​Graphene coated copper and silver coated copper have essential differences in conductivity, each with its own advantages and disadvantages, and their applicable scenarios are also different.
