Dear Colleagues,

I have synthesised BSCCO( 2212). by Combustion method.

But I am not getting Levitation effect by using Liquid Nitrogen.

So, I think the transition temperature is bellow 77°K.

In literature, I find the transition temperature to be 85°K.

Can anyone please suggest me, what may be the fault and what can be done?

Thanks and Regards

N Das
