Preparation method of gallium phosphate target material and preparation method of 68Ge
The invention relates to the technical field of medical treatment, particularly provides a preparation method of a gallium phosphate target material and a preparation method of 68Ge, and aims to solve the problem of low production efficiency of 68Ge caused by the problems of difficulty in target material preparation, more impurities, higher requirements on light beams and the like of the conventional target material for producing 68Ge. The preparation method of the gallium phosphate target material comprises the following steps: S1, putting gallium phosphate powder into a target material mold, and sintering, so that the gallium phosphate powder forms a gallium phosphate crystal; and S2, putting the gallium phosphate crystal into a metal tank for packaging to prepare the gallium phosphate target material. According to the invention, gallium phosphate is adopted as an irradiation target material, so that the target material has a relatively high melting point and relatively high thermal stability, can be suitable for a high-beam accelerator, and is more suitable for commercial large-scale production; according to the method, copper/silver can be prevented from being used as a substrate of the target material, copper/silver impurities are prevented from being introduced in the target melting process, radioactive impurity ions introduced in the irradiation process of the target material can be reduced, and the separation difficulty is reduced.
本发明涉及医疗技术领域，具体提供一种磷酸镓靶材的制备方法及68Ge的制备方法，旨在解决现有的用于生产68Ge的靶材因存在靶材制备困难、产生杂质较多、对光束要求较高等问题而导致68Ge的生产效率不高的问题。本发明的磷酸镓靶材的制备方法包括以下步骤：S1：将磷酸镓粉末放入靶材模具中，进行烧结，以使磷酸镓粉末形成磷酸镓晶体；S2：将磷酸镓晶体放入金属罐中进行封装，制得磷酸镓靶材。本发明采用磷酸镓作为辐照靶材，使得靶材具有较高的熔点和较高的热稳定性，能够适用于高束流加速器，更适用于商业规模化生产；能够避免使用铜/银作为靶材的基底，避免在溶靶过程中引入铜/银杂质，并能减少靶材在辐照过程中引入放射性杂质离子，降低了分离难度。
