far infra rays/bio ceramics

[yinyang]

Hi all, I need a little help here please? Please can somebody answer my question with regards to bio ceramics? I am looking for a way to produce a ceramic that will emitt far infra rays. It would be used in the aquatic scene for biological filtration in a form of trickle towers.But what I need to know is..... what ceramics do I need and their quantities? And also the mineral oxide contents?

Thanks in advance....

Regards
