Model JDH-10 uses high-temperature calcination synthesis 

 Microwave sintering of microwave irradiation instead of the traditional heat source. Uniformly mixed materials or pre-suppress the forming of the billet by itself on the absorption of microwave energy (or dissipation) up to a certain high temperature, causing the combustion synthesis reaction or complete sintering process. compare it with the traditional technology, belong to two very different heating methods, microwave sintering has its own characteristics of microwave dielectric heating principle, chemical raw materials into the microwave electric field, in which the polar molecules and non- polar molecules caused by polarization into a dipole directed in accordance with the direction of electric field Since the electric field is an alternating electric field, so dipoles with the electric field changes caused by the rotation and vibration, for example, the frequency of 2450MHZ per second 200 million to 50 million times the rotation and vibration, resulting in the effect of friction between similar molecules, which absorb the energy of the electric field and heat and the object itself becomes the heating element. ignition ignition is always from the sample when heated in the traditional way, surface, burning from the surface to sample the internal dissemination of the final completion of the sintering reaction using microwave radiation, microwave there is a strong penetrating power, it can go deep into the sample internal first rapid rise of the sample center temperature high reach fire caused by the combustion synthesis. sintering wave along the radial direction from the inside to spread, which can make the whole sample is almost evenly heating the final completion of the sintering reaction. microwave ignition ignition temperature gradient in the sample (dT / dt) is much smaller than conventional ignition. In other words, the microwave sintering process, sintering wave propagation than conventional heating methods are much more uniform. tantalum metal using microwave radiation to the 1300-2000 `C high temperature sintering into ceramic.
