Metallized isolated scintillation ceramic array structure and preparation method thereof
The invention discloses a metallized isolated scintillation ceramic array structure and a preparation method thereof. The scintillation ceramic array structure comprises a scintillation ceramic block,the scintillation ceramic block is provided with a plurality of cutting grooves which are communicated in a criss-cross mode, the cutting grooves divide the upper surface of the scintillation ceramicblock into scintillation ceramic array elements which are distributed in an array mode, and each cutting groove is filled with a sintering type high-density metallization isolation layer. The invention also discloses a preparation method of the scintillation ceramic array structure. The preparation method comprises the following steps: cutting criss-cross communicated cutting grooves in the surface of the scintillation ceramic block to form the scintillation ceramic array structure; immersing the scintillation ceramic array structure into the high-density metallized slurry; performing high-temperature sintering; taking out the scintillation ceramic array structure for cooling after high-temperature sintering; and finally, grinding the array surface of the scintillation ceramic array structure. Scattering of X-rays and secondary fluorescence scattering can be reduced, information distortion of array elements can be prevented, and therefore the resolution of the detector is improved.
本发明公开了一种金属化隔离的闪烁陶瓷阵列结构及其制备方法，所述闪烁陶瓷阵列结构包括闪烁陶瓷块，所述闪烁陶瓷块上设有多条纵横交错连通的切槽，切槽将闪烁陶瓷块的上表面分割为阵列分布的闪烁陶瓷阵元，各条切槽内填充烧结型高密度金属化隔离层；还公开了闪烁陶瓷阵列结构的制备方法：在闪烁陶瓷块的表面切割出纵横交错连通的切槽，形成闪烁陶瓷阵列结构；接着将闪烁陶瓷阵列结构浸入高密度金属化浆料中；再进行高温烧结；高温烧结后取出闪烁陶瓷阵列结构进行冷却；最后闪烁陶瓷阵列结构的阵列面进行研磨处理。本发明能够减少X射线的散射以及二次荧光散射，能够防止阵元的信息失真，从而提高了探测器的分辨率。
