Dear all,

I am the postgraduate. I would like to know where can manufacture the
piezoelectric nanocomposites, such as PZT/MgO.(5, 10, 15, 20MgO). Since many
ceramic companies cannot produce nanocomposites. I would like to have some
technology exchange with the other research centres or some co-operation. Please
contact me if anyone know where I can contact. Thankyou. My e-mail is
[email protected].
