Ceramic material for MAX-phase fuel cladding element, pipe fitting and preparation method thereof
The invention discloses a ceramic material for an MAX-phase fuel cladding element, a pipe fitting and a preparation method of the pipe fitting. The MAX phase ceramic material is prepared from the following raw materials in parts by weight: 100 parts of MAX phase ceramic powder; 0.1-5 parts of a sintering aid; 0.5-5 parts of a dispersant; 0.5 to 5 parts of a binder; the preparation process of the fuel cladding thin-wall pipe fitting comprises the following steps: adding the MAX-phase ceramic material into a mold of the fuel cladding thin-wall pipe fitting, and carrying out cold isostatic pressing to obtain a pipe blank of the fuel cladding thin-wall pipe fitting; and sintering the tube blank in a protective atmosphere. According to the preparation method, the fuel cladding thin-wall pipe fitting with the large length-diameter ratio can be effectively prepared, and the prepared fuel cladding thin-wall pipe fitting has the advantages of being uniform in size, high in densification degree, excellent in mechanical property and the like.
本发明公开了一种MAX相燃料包壳元件用陶瓷材料、管件及其制备方法。其中，一种MAX相陶瓷材料，包括如下重量份的原料:MAX相陶瓷粉料100份；烧结助剂0.1‑5份；分散剂0.5‑5份；粘结剂0.5‑5份；一种燃料包壳薄壁管件的制备过程为：采用上述的一种MAX相陶瓷材料加入到燃料包壳薄壁管件的模具中，进行冷等静压，获得燃料包壳薄壁管件的管坯；再将管坯在保护气氛下进行烧结即可。本发明可以有效制备出具有较大长径比的燃料包壳薄壁管件，且制备得到的燃料包壳薄壁管件具有尺寸均匀、致密化程度高、力学性能优异等优点。
