Description
技术领域
本发明属于防辐射技术领域，具体涉及一种用于木星环境辐射屏蔽的高熵陶瓷钽酸盐材料的制备方法。可应用于深空探测领域，具有十分重要的应用前景。
背景技术
近年来，随着航天事业的不断发展，由近地向深空范围的探索逐步进行。木星作为太阳系中最大的行星，拥有数量众多的卫星，对其探测有助于解决太阳系形成、演化等重要科学问题
因此，木星探测逐渐成为深空探测的焦点和热点之一。木星磁场强度是地球的20倍，其辐射带质子的能量可达到几GeV，高能电子通量则比地球辐射带高2～3个数量级，电子的最高能量可达到1GeV，而地球辐射带中的捕获电子能量一般小于10MeV。与其他深空探测任务相比，木星探测的高能粒子具有能量大、通量大、能谱硬等特点。面对如此恶劣的辐射环境，木星探测器中的抗辐射加固设计至关重要。
目前为止，国外已有多颗探测器造访过木星，其中以环绕形式探测木星的航天器“朱诺号”Juno在木星极轨轨道对其进行全方位探测。另外，NASA和ESA还有多个正在实施的木星探测计划，如JUICE和JEO等。针对木星环境高能电子和质子，对辐射屏蔽舱体外层材料进行设计，既要满足高能粒子的阻挡，又要具有一定的支撑能力；既要保持材料的重量适中，又要尽可能低花费。例如：Juno初期利用1mm钽板加固，但钽板太薄、结构强度不达标；中期利用钽板夹铝蜂窝复合板，但成本昂贵，工艺繁杂导致最终放弃；后期只能将加厚钛合金板的作为最后的选择。因此，如何实现钽基材料支撑行屏蔽性能共存仍然迫切需要解决的问题。一般对于木星强辐射环境，利用高原子序数(Z)材料(钽、钨、钛等)进行屏蔽是较好选择。对于高能电子，其与物质作用会产生更强的轫致辐射。总体而言，低Z序数材料屏蔽高能质子更有效，高Z材料屏蔽高能电子和轫致辐射更有效。因此，高能质子与电子屏蔽的过程是不同原子序数材料相互辅助相互配合的过程。
自2004年中国台湾的叶均蔚教授年正式提出了高熵理念以来，这种理念突破了传统合金的设计思路，开拓了一条全新材料合成道路。2015年Rost等人以金属氧化物为原料，首次合成高熵氧化物，并且将大于等于5种阳离子或阴离子以等比例或近等比例相互固溶而形成的一种新型多元素陶瓷材料定义为高熵陶瓷。高熵陶瓷材料的短程有序，长程无序，在晶胞尺寸下实现多尺度元素分布，实在微尺度下高、低Z元素混合。通过调整元素不均匀性导致的化学复杂性，可以在高辐射环境中调节缺陷的产生和演变，为辐射防护应用设计结构材料提供了独特的机会。
目前研究证明纯钽材料对深空环境中的带电粒子具有优异的屏蔽效果，但钽的结构强度差，价格相对昂贵，无法实现纯钽板大面积应用。
单一钽板片屏蔽高能电子会产生高能韧致辐射，同样对电子器件有损伤，叠加效应甚至比未屏蔽的损伤更大，因此需要低原子序数材料进行配合。
发明内容
本发明合成高熵陶瓷钽酸盐，利用高熵陶瓷的高硬度、高密度等特有性质，实现钽基辐射防护材料的制备。
本发明利用高熵陶瓷的元素灵活调配性，种类多样性，实现同一晶格中的高低原子序数配合，减少带电粒子穿过材料的剩余计量。
本发明一种用于木星环境辐射屏蔽的高熵陶瓷钽酸盐材料的制备方法，所述制备方法是按下述步骤进行的：

一种上述方法制备的高熵陶瓷钽酸盐材料。
本发明首次利用高熵陶瓷钽酸盐作为高能质子与电子的辐射防护材料。利用高熵钽酸盐的高熵特性，解决纯钽材料的支撑性差的问题。
本发明利用高熵陶瓷是高原子序数Ta、La等元素与低原子序数非金属O和中原子序数Ti、V等元素的集合体，一方面减少电子及韧致辐射能量，消耗质子能量，另一方面晶胞内的不同Z的元素可以对辐射能量逐级消耗，直到消耗完或穿透材料。
本发明中高熵材料元素混乱，增加材料的原子堆积密度，从而增加材料密度，提高带电粒子与原子的碰撞概率；
本发明中较大的熵值导致材料具有更好的稳定性，赋予了材料优异的机械性能和稳定性。
本发明利用高熵陶瓷钽酸盐作为高能质子和高能电子的屏蔽材料，通过调整元素种类，压片工艺以及高熵钽酸盐的烧结参数可以有效控制高熵钽酸盐屏蔽性能。
本发明能对深空探测高能带电粒子的辐射防护，长期辐射环境下的抗辐射，和材料结构性能。高熵钽酸盐中包含对电子和韧致辐射有利屏蔽的高原子序数元素、对质子屏蔽有利的低原子序数元素，可实现能量逐级衰减中Z元素。因此，通过灵活的元素调变和精准的元素种类选择决定的其对电子与质子的高效屏蔽。高熵结构的四大效应导致其耐腐蚀、硬度大、结构性能稳定，因此长期处于辐照环境下仍然保持较好的稳定性，具有优异的抗辐射性能。同时，钽酸盐改变了纯钽材料的结构性差、价格昂贵，使用受限的弊端。因此，高熵钽酸盐材料代替了传统纯钽的防护方式，开发了一种新形式的含钽屏蔽材料，为辐射防护领域材料的开发提供了新的方法。
