Tunnel Microwave Kaolin Sintering Machine

Microwave sintering equipment can be used to sinter various high quality ceramics, lithium cobalt oxide, silicon nitride, silicon carbide, aluminum oxide, aluminum nitride, zirconia, magnesium hydroxide, aluminum, zinc, kaolin, cobalt sulfate, cobalt oxalate, five Vanadium oxide, phosphogypsum/gypsum, etc.; sintered electronic ceramic devices: PZT piezoelectric ceramics, varistors, etc.

The Si_3N_4 ceramic was sintered by microwave sintering technique and conventional pressureless sintering technique. The composition and microstructure of Si_3N_4 samples sintered by different techniques were studied by XRD and TEM. The flexural strength and fracture toughness of the two samples were measured by three-point bending and indentation. The results show that the introduction of N 2 gas pressure can effectively control the decomposition of Si_3N_4 during microwave sintering. Microwave sintering can greatly reduce the densification temperature of Si_3N_4, increase the phase transformation speed, shorten the sintering time, and improve the mechanical properties.

The propagation of the sintering wave during microwave sintering is much more uniform than the conventional heating method. The metal is sintered to a ceramic by microwave irradiation to a high temperature of 1300-2000 ° C. Experiments have shown that when the compactness of the sample is high, the propagation rate of the combustion wave caused by the conventional heating method is greatly reduced, and it is not natural because of "self-extinguishing". However, if microwave irradiation is used, since the temperature rise is the result of the absorption (or diffusion) of the microwave energy by the reaction substance itself, as long as the microwave source continuously supplies energy, the sample temperature will quickly reach the ignition temperature (T1). Once the reaction is initiated, the heat released causes the sample temperature to rise further to the combustion temperature (T2), and the ability of the sample to absorb microwave radiation also increases, which ensures that the reaction can be maintained at a sufficiently high temperature (T3>T1). Carry on until the reaction is complete. Microwave combustion synthesis or microwave sintering is a process that can be controlled. That is to say, we can artificially control the propagation of combustion waves by adjusting a series of parameters according to the requirements of the nature of the product. This is a significant advantage of microwave combustion synthesis over conventional techniques. Microwave power can be adjusted directly by using a microwave source with adjustable power to control the absorption (or dissipation) of microwave energy by the sample.
