Tungsten boat is made from Tungsten sheet through a process of cutting, bending, welding and riveting. We can manufacture customized products according to your requirements.

tungsten boat is mainly applied in the manufacturing process of wolfram powder by anhydrous wolframic acid. Sintering W-boat is an important carrier for making powder. Or load ammonium paratungstate (APT) in firing W-boat to make tungsten powder, the APT is white crystal, which include schistose and acicular, it is applied in the manufacturing process of tungsten metal powder by anhydrous wolframic acid or blue tungsten oxide.

At the time of firing, sintering tungsten boat can remove a portion of the harmful impurities, such as sulfur, potassium, sodium and others. This type of W-boat reduces the adverse effects of harmful ingredients (water, oxygen, nitrogen) of the product under vacuum sintering. It is in favor of eliminating the adsorbed gas and the residual gas of the pores which can promote post-sintering shrinkage.
