Ceramic balls

Ceramic balls

(OP)
I need various type of half inch ceramic balls (alumina, zirconia, silicon carbide and nitride) for laboratory uses. Can anyone help with getting bearing grade ceramic balls?

RE: Ceramic balls

Ceratec Technical Ceramics in the Netherlands delivers bearing grade ceramic balls.

Materials they can deliver are: alumina, zirconia, silicon nitride, silicon carbide, rubin and sapphire.

more info on www.ceratec.nl

RE: Ceramic balls

You might find that only Si3N4 is listed as bearing grade. SiC and ZrO2 can be found in pretty good quality at houses that make them as a primary product. ZrO2 balls are used a great deal in powder and ink milling operations. Get yttria stabilized zirconia.

RE: Ceramic balls

Cerbec makes silicon nitride balls specifically for bearings.  They also link to bearing manufacturers off their site at http://www.cerbec.com/.
