  • Sintering Process of Refractory Metal Powder Refractory

    Sintering is a hot processing method to produce refractory metals. First, heat the powder compact to the sintering temperature for a certain period of time. Then, wait it to cool down and the refractory materials with required functions will be produced. Sintering makes the porous powder compact into a product with certain structures and
