In the cemented carbide, our most commonly used three functions of tantalum and niobium is to inhibit grain growth, improve alloy red hardness and fatigue resistance. We must understand that the characteristics of the tantalum and niobium comparison, is basically a comparison of the two elements. Si...

Tantalum and niobium are the same family of elements,the outermost electrons are the same,and the chemical activity is basically the same.Tantalum and niobium are the core structure,lattice constant is close to their thermal conductivity,linear expansion coefficient are also very close. In addition,...

In recent years due to tantalum raw material water up, so that the price of tantalum containing alloy all the way up. But because people think that the role of tantalum in the carbide can not be replaced with other raw materials, so the face of the price rise is seem powerless. We know that the mate...
