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 ...

Titanium dioxide has the characteristics of high chemical stability, non toxicity, and good photoelectric performance, especially rutile titanium dioxide has high surface activity, which is very suitable for battery material modification. Like polyethylene glycol, the introduction of titanium dioxide is also to compensate for the insufficient energy density and rate performance of lithium iron pho...
