Ceramic shell, preparation method and X-ray tube
The invention relates to the technical field of aluminum oxide ceramic preparation, in particular to a ceramic shell, a preparation method and an X-ray tube. A binder is added into formula powder, grinding and pulping are conducted, and slurry is obtained; granulating the slurry to obtain a granulated material; carrying out isostatic pressing on the granulated material, and processing the granulated material into a blank with an accurate size; the blank adsorbs water molecules in the closed space until the blank is in a saturated state, and an infiltrated blank is obtained; the infiltrated blank is put into a rubber sleeve, and then isostatic pressing is performed once, so that the density of the blank can be obviously improved, the elasticity aftereffect of the blank is reduced, the generation of microcracks is weakened, the consistency of the density of the blank can be improved to different degrees, and the density and the uniformity of the blank are improved; and finally, carrying out high-temperature calcination on the prefabricated blank to obtain the ceramic shell with a uniform structure and high compactness. The problem that the preparation qualification rate of the X-ray tube porcelain shell is low is solved.
本发明涉及氧化铝陶瓷制备技术领域，尤其涉及一种陶瓷瓷壳、制备方法及X射线管，通过向配方粉料中加入粘结剂，并进行研磨制浆，得到浆料；对浆料进行造粒，得到造粒料；将造粒料进行等静压压制，并加工为精确尺寸的坯件；使坯件在密闭空间吸附水分子至饱和状态，得到浸润坯件；将浸润的坯体装入橡胶套中，再进行一次等静压压制，可以使坯件的密度明显提高，坯体弹性后效减小，减弱微裂纹产生，且可在不同程度上提升坯件密度的一致性，使坯件的密度、均匀性均得到改善；最后，将预制坯件进行高温煅烧，得到结构均匀高致密性的陶瓷瓷壳。解决X射线管瓷壳制备合格率低的问题。
