According to the growth of different kinds of diamond powder catalyst column can be divided into the grinding powder column and cutting powder column 2 series. Are made of pure fossils toner and catalyst metal powder mixing, pressing, reduction of sintering.Grinding diamond series powder made from catalytic column with optimum graphite and catalyst, with a concentrative distribution, uniform particles, good combination, high density, low oxygen content, impurity content, high conversion rate, less in the domestic leading level, and can be adjusted by the raw material formula and manufacturing process of different size and grade of diamond synthesis.Cutting class diamond powder catalyst column series adopt strict craft, the column of the synthetic diamond powder, with a complete crystal sha...
