Hello Mr. Wang,

I hope this helps if you need PZT wafers then you can call Roger
Milewski at Motorola, it was just bought by another company so the name
is different, his number is 505-348-4260.
If you need a thin film of PZT or PLZT on another substrate they can not
help, but may be able to tell you where.

And again we can help with a dicing blade to cut your PZT material. We
have lots of experience with cutting PZT for medical ultrasound or for
print heads.
