Class I and Class II materials are two fundamental concepts in the field of materials science, which are used to describe the crystal structure types of materials and are often applied in the research of materials such as semiconductors and metals. So, how do we distinguish between Class I materials and Class II materials? A simple method is to distinguish based on the density of the material. Com...

Dielectric materials are electrical insulation materials that can store charges. The dielectric constant is an important performance indicator of dielectric materials, used to measure the response of materials to charge storage capacity in an electric field. The dielectric constant is divided into two types: relative dielectric constant and absolute dielectric constant, among which the relative di...

With the continuous development of nanotechnology, nano metal ultrafine powders have been increasingly widely used. However, during storage and transportation, nano metal ultrafine powders also face some problems, such as poor thermal stability and easy oxidation and heating. Therefore, we must take some measures to ensure the safe storage and transportation of nano metal ultrafine powders. In ord...
