Foamed ceramic foamed by using boron carbide and preparation method thereof
The invention belongs to the field of ceramic materials, and particularly relates to foamed ceramic foamed by boron carbide and a preparation method thereof.The foamed ceramic is prepared from quartz sand serving as a main body material, sodium carbonate serving as a fluxing agent, periclase and albite or potassium feldspar serving as viscosity modifiers, ferric oxide serving as an oxidizing agent and boron carbide serving as a foaming agent. The sintering temperature is 810 to 890 DEG C, and the sintering time is 35 to 65 minutes. The invention further discloses a preparation method of the foamed ceramic, the method has the remarkable advantage of low sintering temperature, and the manufacturing cost is far lower than that of the prior art. The foamed ceramic prepared by the preparation method disclosed by the invention has relatively high total porosity, closed porosity and compressive strength at the same time, and has excellent heat preservation, sound insulation, water resistance and humidity resistance due to the fact that pores in the foamed ceramic are independent from one another and are not communicated with one another.
本发明属于陶瓷材料领域，具体涉及一种利用碳化硼发泡的泡沫陶瓷及其制备方法，所述泡沫陶瓷以石英砂作为主体材料，以碳酸钠作为助熔剂，以方镁石和钠长石或钾长石作为粘度调节剂，以氧化铁作为氧化剂，以碳化硼作为发泡剂，烧结温度为810～890℃，烧结时间为35～65min。本发明还公开了上述泡沫陶瓷的制备方法，该方法具有烧结温度低的显著优点，制造成本远低于现有技术。本发明所制备的泡沫陶瓷同时具有较高的总孔率、闭孔率和抗压强度，由于其内部各孔彼此独立不连通，故具有优异的保温、隔音、防水、防潮性能。
