Composite phase honeycomb ceramic and method of controlling expansion coefficient of ceramic
The invention belongs to the field of new material ceramics, and particularly relates to a composite phase honeycomb ceramic and a method for controlling the expansion coefficient of ceramic. The method mainly comprises the following steps: weighing corresponding mass of Al2O3, SiO2 and Li2CO3 raw materials, and uniformly mixing the Al2O3, SiO2 and Li2CO3 raw materials; adding a bonding additive into the mixed raw materials, uniformly mixing, and extruding honeycomb ceramic; performing rubber discharging on the extruded sample in a calcining furnace at the temperature of 600-650 DEG C, and performing heat preservation for 4-10 hours; and putting the glue-discharged sample into a sintering furnace to be synthesized and sintered at the temperature of 1350-1450 DEG C for 4-8 hours; and testing thermal expansion coefficient after sintering.
本发明属于新材料陶瓷领域，具体涉及一种复合相蜂窝陶瓷以及控制该陶瓷膨胀系数的方法。该方法主要步骤：称量相应质量的AlO、SiO和LiCO的原料混合均匀；将混合好的原料中加入粘结添加剂混合均匀后挤出蜂窝陶瓷；将挤出的样品在煅烧炉中排胶温度600‑650℃，保温时间为4‑10小时；将排完胶的样品放入烧结炉中合成烧结，温度1350‑1450℃，时间为4‑8小时。烧结后测试热膨胀系数。
