Corrosion-resistant aluminate neutron absorbing material and preparation method thereof
The invention relates to a corrosion-resistant aluminate neutron absorbing material and a preparation method thereof. The chemical components of the aluminate neutron absorbing material comprise (Re2O3) X-(Al2O3) 1-X, wherein Re is selected from at least one of rare earth elements, and X is equal to 0.2-0.8. The neutron absorbing material is a stable structure compound formed by taking a rare earth element as a neutron absorber and aluminum and oxygen as structure stabilizers, can meet the requirements of a fault-tolerant neutron absorbing material with a long service life, and is excellent in mechanical property, resistant to subcritical water or steam corrosion, high in neutron absorber content, and good in thermal shock performance; and the neutron absorbing material is an ideal nuclear reactor control rod absorbing body material.
本发明涉及一种耐腐蚀铝酸盐中子吸收材料及其制备方法，所述铝酸盐中子吸收材料的化学成分包括(Re2O3)X‑(Al2O3)1‑X，其中Re选自稀土元素中的至少一种，X=0.2～0.8。上述中子吸收材料以稀土元素为中子吸收剂，以铝和氧为结构稳定剂形成的稳定结构化合物，能够满足作为长寿期的容错型中子吸收材料的需求，力学性能优良、耐亚临界水或蒸气腐蚀、中子吸收剂含量高、热震性能好，是一种理想的核反应堆控制棒吸收体材料。
