Lead-rich slags富铅渣
1.Lead-rich slags with different levels of PbO content have been prepared in laboratory.选用实验室制备的不同PbO含量的富铅渣与工业化生产的铅烧结块在竖管炉中用石墨坩埚进行还原反应对比试验。
2.Lead-rich slags containing different level of PbO concentrations have been prepared in laboratory.选用实验室制备的不同PbO含量的富铅渣,确定富铅渣的孔隙率和密度、软化温度、微观结构和相成分。
3.Lead-rich slags containing different CaO/SiO2 ratio have been prepared in laboratory.制备不同CaO/SiO2比率的富铅渣,在实验室竖管炉中用石墨坩埚进行还原反应对比试验研究。
3)Removing lead and concentrating sulfur脱铅富硫
4)lead-rich atmosphere富铅气氛
1.The effect mechanism of PbO atmosphere was proposed and the results revealed that the ceramics sintered in lead-rich atmosphere had better piezoelectric properties, especially the ceramics containing 10%PMN showed the optimized results of ε~T_(33)/ε_0=1 000, tan δ=0.实验表明在富铅气氛的作用下,PZMN体系具有较优的性能,尤其是x=0。
2.10PbTiO 3 pre-calcined powders and ceramics were prepared by columbite metho d and sintered with lead-rich atmosphere.实验表明在富铅气氛的作用下,微量氧化铅欠缺的初始粉体所制备出的陶瓷具有较好的介电性能,尤其是当初始粉体中氧化铅欠缺5%时的陶瓷具有最大的峰值介电常数。
5)enriched lead富集铅
6)bing ore富铅矿(地)

铅-铅测年分子式：CAS号：性质：238U和235U两个母体铀同位素的特性实质相同，所产生的放射性成因206,207Pb的方程可合并为（207Pb/206Pb）=[(235U/238U)]（t-1）。235U/238U现在的比值是1/137.8，利用非放射性成因‘稳定’204Pb作为参考同位素，作（207Pb/204Pb）与（206Pb/204Pb）的Pb-Pb等时线，应用方程计算年龄，式中（207Pb/204Pb）和(206Pb/204Pb)0是初始比值。
