The invention relates to the field of ceramic materials, and particularly discloses a low-temperature sintered aluminum nitride ceramic material, aluminum nitride tape casting slurry and application. The aluminum nitride ceramic material comprises aluminum nitride ceramic powder, a sintering aid A and a sintering aid B, wherein the sintering aid A is one or a combination of more of AlF3, LiF and metal Li powder, and the sintering aid B is one or a combination of more of CaF2, YF3, Y2O3 and Dy2O3; the mass of the sintering aid A is 4-7% of the total mass of the aluminum nitride ceramic powder, and the dosage of the sintering aid B is 2.5-4.5% of the total mass of the aluminum nitride ceramic powder. The aluminum nitride tape casting slurry comprises an organic solvent, a dispersing agent, a defoaming agent, an adhesive, a plasticizer and the aluminum nitride ceramic material. According to the aluminum nitride ceramic product prepared from the aluminum nitride ceramic material, the sintering temperature is reduced to 1300-1450 DEG C, low-temperature sintering is achieved, and the prepared aluminum nitride ceramic product has excellent thermal properties.
本申请涉及陶瓷材料领域，具体公开了一种低温烧结的氮化铝陶瓷材料、氮化铝流延浆料及应用。该氮化铝陶瓷材料包括氮化铝陶瓷粉体、助烧剂A和助烧剂B，助烧剂A为AlF3、LiF、金属Li粉中的一种或多种的组合，助烧剂B为CaF2、YF3、Y2O3、Dy2O3中的一种或者多种的组合；助烧剂A的质量为氮化铝陶瓷粉体总质量的4‑7%，助烧剂B的用量为氮化铝陶瓷粉体总质量2.5‑4.5%。该氮化铝流延浆料包括有机溶剂、分散剂、消泡剂、粘合剂、增塑剂以及上述氮化铝陶瓷材料。本申请采用上述氮化铝陶瓷材料制得氮化铝陶瓷制件，烧结温度降至1300‑1450℃，实现低温烧结，且制得的氮化铝陶瓷制件具有优良的热学性能。
