Abstract
The invention relates to a method for sintering green bodies of tungsten metal plates, molybdenum metal plates, tungsten alloy plates or molybdenum alloy plates. The method comprises the following steps of placing a filler and the green bodies of the tungsten metal plates, the molybdenum metal plates, the tungsten alloy plates or the molybdenum alloy plates into a sintering container in a staggered way; filling the left space in the sintering container by using the filler to guarantee no displacement of the green bodies of the tungsten metal plates, the molybdenum metal plates, the tungsten alloy plates or the molybdenum alloy plates in the movement of the sintering container; placing the sintering container into a sintering furnace at the temperature of 1000 to 1600 DEG C for one to ten hours of heat preservation. The method has the advantage that multiple laminated green body plates of tungsten or molybdenum alloy powder can be sintered every time.
