Nano silver is a kind of new high technology products, It hasvery strong antimicrobial and kill bacterial functions, so itwidely  use for antimicrobial products, for example , it cankill  coli bacillus and staphylococcus aurous and many othermicrobe. melting point is  100âÂ??Â??, it can make conductivepaste and sinter under low temperature.

1.  Nano silver has big specific surface, so it hasgood catalyst active.

2.  Nano silver particle and appearance

       Under TEM the size is :

                                          20-30nm  around 70%

                                          30-40nm  around 15%

                                          40-50nm  around 10%

                                          50-60nm  around 5%

     Nano  silver particle is likea ball.

3. Nano silver specific surface

     11.5945±0.1302m2/gãÂ??Â??

4. Laser particle list:

    Use laser to test size, the conclusion is5.6-82.3nm is 100%

5. Nano silver crystalling phase analysis

    The crystalling phase analysis conclusionis:

    84% is cube, 16% is hexahedron , the size ofcube nano silver is 145A0

6. Tap and loosen density
