Electronic grade titanium dioxide
Product Introduction
Electronic grade titanium dioxide belongs to non - pigmentary titanium dioxide. It requires a high level of purity (titanium dioxide content), and other indicators also need to meet stringent requirements. Firstly, it can be used in capacitors. Secondly, it can be applied in ceramics, enamel, and electric welding, among others.
