Radiation-resistant rare earth doped fluorapatite cement and preparation method thereof
The invention discloses radiation-resistant rare earth doped fluorapatite cement, which is prepared from the following raw materials in parts by weight: 3 to 6 parts of Ca (NO3) 2.4 H2O, 1 to 3 parts of Tween 80, 1 to 3 parts of CTAB (Cetyltrimethyl Ammonium Bromide), 8 to 14 parts of Na3Cit.2H2O, 1 to 2 parts of NaF, 1 to 4 parts of (NH4) 2HPO4 and 1 to 3 parts of Ln (NO3) 3 powder. The doped apatite product does not contain impurities and dopants, and the particle size distribution of the apatite nanocrystals is concentrated at about 100 nm through calculation of a Scherrer formula. The apatite crystal quality is high, and the crystallinity of the doped fluorapatite generated by the method through Jade refinement is about 99.5%. In the synthesis process, rare earth elements can fully enter an apatite crystal structure, and uniform distribution of doped elements is facilitated. The hydrothermal coprecipitation method is mature in process, adjustable in reaction time, temperature and reactant proportion, wide in application range and easy for mass production.
本发明公开一种耐辐射稀土掺杂氟磷灰石水泥，它包括以下重量份的原料：3‑6份Ca(NO3)2·4H2O，1‑3份Tween80，1‑3份CTAB，8‑14份Na3Cit·2H2O，1‑2份NaF，1‑4份(NH4)2HPO4，1‑3份Ln(NO3)3粉末。掺杂磷灰石产物中没有杂质和掺杂物，通过谢乐公式计算得到磷灰石纳米晶体粒径分布集中在100nm左右。磷灰石结晶质量高，通过Jade精修得到此法生成的掺杂氟磷灰石结晶度在99.5％左右。在合成过程中，稀土元素能够充分进入磷灰石晶体结构中，有利于掺杂元素的均匀分布。水热共沉淀法工艺成熟，反应时间、温度、反应物比例均可调节，使用范围广，易于大量生产。
