Non-pressure solid-phase sintering preparation method of porous silicon carbide ceramic
The invention discloses a pressureless solid-phase sintering preparation method of multi-channel silicon carbide ceramics, which comprises the following steps of: preparing a silicon carbide sheet, namely a casting diaphragm, with the thickness meeting the requirement by adopting a tape casting method, cutting the casting diaphragm according to the size of a mold, placing the casting diaphragm on the mold, installing the mold, pressing by using an isostatic press to obtain a molded biscuit, and sintering the molded biscuit to obtain the multi-channel silicon carbide ceramics, namely the pressure-free solid-phase sintering preparation method of the multi-channel silicon carbide ceramics. The finished multi-channel silicon carbide ceramic product has the advantages of impact resistance, corrosion resistance, reliable sealing, large heat dissipation area and difficulty in breakage, a plurality of multi-channel silicon carbide ceramic products can be assembled together to form heat exchange equipment, and the problem of high processing cost of a block hole type heat exchanger is solved.
本发明公开了一种多孔道碳化硅陶瓷的无压固相烧结制备方法，采用流延成型法，先制备出符合要求厚度的碳化硅薄片即流延膜片，将流延膜片根据模具尺寸裁剪，并在模具上摆放好，将模具安装后，再经过等静压机压制，制得成型素坯，成品多孔道碳化硅陶瓷制品，具有耐冲击，耐腐蚀，密封可靠，散热面积大，不易断裂的优点，可以多个组装在一起，形成换热设备，解决了块孔式换热器加工成本高的问题。
