    铅块中铅离子的结晶反应现象!
    来源: 发布时间:2020-04-30

      位于玻璃表面的一个Pb2+离子,只有—·头受氧离子极化,铅块朝外的一头呈一定程度的金属性,这必然对玻璃的表面行为也发生特定作用。结晶PbO四方晶胞结构中Pbc+离子受氧离子的极化和变形是更为明显的。在形成个PbO四方晶胞的结晶进程中,头四个氧离子向尸b’+离子靠拢,形成两极。铅玻璃向铅离子靠拢的后四个氧离子,因铅离子的“两极性”而与铅离子保持比头四个氧离子较大的距离。
      For a Pb2 + ion located on the surface of glass, only the head is polarized by oxygen ions, and the head of the lead block towards the outside is metallic to a certain extent, which will inevitably have a specific effect on the surface behavior of glass. The polarization and deformation of PBC + ions in the tetragonal cell structure of crystalline PbO are more obvious. In the crystallization process of forming the first PbO tetragonal cell, the first four oxygen ions move towards the corpse B '+ ions and form two poles. The last four oxygen ions of lead glass close to lead ions keep a larger distance from lead ions than the first four oxygen ions because of the "polarity" of lead ions.
      x射线结构分析数据得出前四个氧离子与铅离子的距离为2.3A,铅块后四个氧离子与铅离子的距离为4.29人,后者是前者的近两倍,反映出Pb2+离子的极化作用和变形。二元PbO—SiO2玻璃中PbO的浓度较小时,Pb:+离广如同Na20—SiO2玻璃中的Na+离子一样,起网络外体功能;们PbO浓度大时,显然出现Pb:+/尸b:+平衡,Pb真+离子以[PbO:)结构团进入网络,因而一直到浓度仍能形成玻璃。
      X-ray structural analysis data show that the distance between the first four oxygen ions and lead ions is 2.3A, the distance between the last four oxygen ions and lead ions is 4.29 people, the latter is nearly twice the former, reflecting the polarization and deformation of Pb2 + ions. When the concentration of PBO in binary pbo-sio2 glass is small, the dispersion of Pb: + is the same as that of Na + ion in na20-sio2 glass, which functions as an external network; when the concentration of PBO is large, the equilibrium of Pb: + / corpse B: + appears obviously, and the real + ion of Pb enters the network as a [PbO:] structure group, so the glass can still be formed up to the highest concentration.
    射线防护器材
      铅块作为原子序数较高的金属,所制成的铅板就是一种对射线有较好屏蔽作用的材料,起到类似作用的还有铅复合板、铅防护服、铅帽、铅面罩、铅屏风、铅眼镜、铅玻璃等等.在射线防护行业,铅板也称为防辐射铅板,射线防护铅板,另外铅板还可以应用在工业探伤、抗酸防腐蚀、隔音、电池、工业制品配重等方面,不同行业里称为探伤防护铅板、隔音铅板、阳极铅板等.
      As a metal with higher atomic number, lead block is a kind of material with better shielding effect on ray. Lead composite plate, lead protective clothing, lead cap, lead mask, lead screen, lead glasses, lead glass and so on play a similar role. In ray protection industry, lead block is also called radiation protection lead plate, ray protection lead plate, In addition, the lead plate can also be used in industrial flaw detection, acid and corrosion resistance, sound insulation, batteries, industrial products counterweight, etc. in different industries, it is called flaw detection protection lead plate, sound insulation lead plate, anode lead plate, etc
