I need to fabricate small sized AgAgCl reference electrodes with capillaries with IDs of ~1 mm and I'm looking for a supplier selling porous ceramic frits/rods with ODs of ~1 mm. Does anyone know a supplier and/or the actual composition of the porous ceramics used in reference electrode? Is it Al2O3 or AlN or others?
Thanks a lot!
Hello Stefan Scheiblbrandner ,
The following materials are commonly used for fabricating frits in REs:
- CoralPor™
- Vycor
- Polyethylene
- Teflon
- Electro-porous KT glass
- silicon-oxide based ceramic
- aluminium-oxide based ceramic
