Development of substitutes for lead pigment;

In ink jet printing, lead based pigments and lead-contained drying agents are used; lead compounds are used as stabilizing agent in PVC coating; and lead contained attachments or decorations may be used for garments; and all these may lead to the content of lead exceeding the criteria, which should arouse people s attention.

Analysis on current development and economic situation of China inorganic pigment industry 2008

This paper narrates present status of interna- tional inorganic pigment manufacture and demand, fore- casts development trend of the products and gives the strat- egy to develop the industry.

This paper introduces functions and methods of surface treatment of inorganic pigment; analyzes mechanism of operation and tells selection of surfactants and treatment methods.

Study of Sn-Zn Lead-free Solder by Alloying;

Study on interface and shear behavior in lead-free solder joint;

Rare earths modified Sn-58Bi low-temperature lead-free solders;

Advances in research and application of lead-free solders for electronic and photonic packaging;

Compared with the traditional “Bi-Segregation” invalidation mechanism, the“three-factor method” can explain the causes of lift-off formed or non-formed by all lead-free solders with and without bismuth.

Because of lead poisoning in Sn-Pb solder,it is necessary for our electronicmaterial industry to develop lead-free solders.
