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...

Aluminum powder is a commonly used filler, widely used in fields such as thermal interface materials and industrial coatings. However, traditional aluminum powder has problems such as high viscosity, poor dispersibility, and poor thermal stability, which limit its effectiveness in some special applications. To address these issues, researchers have carried out many modification methods to improve ...

Carbon nanotubes (CNTs) reinforced aluminum composites with unique intragranular dispersion were obtained using ultra short carbon nanotubes, and nanoscale carbon nanotubes were uniformly distributed within ultrafine aluminum grains. Compared with typical CNT/Al composite materials with intergranular carbon nanotube dispersion, this intragranular carbon nanotube/aluminum composite material has str...

Titanium dioxide is mainly divided into three types: plate titanium dioxide, anatase titanium dioxide, and rutile titanium dioxide. Rutile titanium dioxide and anatase titanium dioxide are two important types of titanium dioxide, which are currently the most widely used in the market. However, their properties differ greatly. Difference in Chemical property Titanium dioxide has extremely stable ch...

The sintering of materials involves at least two processes: densification of the body and growth of grains in the body. The longevity of grains is usually achieved through the movement of grain boundaries. According to the classical theory of grain growth kinetics, the difference in free energy between the two sides of a curved grain boundary is the driving force that causes the interface to move ...

After purchasing our company's nano iron oxide powder, the customer found that the particle size was larger during testing. Why is that? Because the particle size of nano powder is very fine, it is easy to agglomerate, so the large particle size tested is the particle size after agglomeration. So how can we effectively disperse nano iron oxide powder? Next, we will introduce how to use ultrasonic ...

The properties of vanadium dioxide: The molecular formula of vanadium dioxide is VO2, with a molecular weight of 82.94. It is a dark blue crystal powder with a monoclinic crystal structure. Insoluble in water, easily soluble in acid and alkali. When dissolved in acid, it cannot generate tetravalent ions, but generates positive divalent vanadium oxide ions. When heated to red heat in a dry hydrogen...
