Zinc Oxide Sinters

[npf]

Hello All,
I need information on zinc oxide sintering for transforming it into hollow spheres ?How it is done ?Information on sintering furnace? Cost involed in the process? Crucial paramters? List of vendors who do sintering
Waiting for your reply

Thanks & Regards

How thick a sphere wall do you need? Do you need very high volumes?

Hello,

Thanks for replying

I dont know the exact volume but around 1 ton .The thickness of the sphere wall will be around 1/2 - 1.0mm.

Try this guy for hollow spheres:

On your own, I could only suggest sputtering or evaporating over a polymerc sphere which you later burn out.

Hello,
Thanks for yr info
I e-mailed the person but I got a reply message which is in different language so couldnt understand it
Anyways do you(or any particular website) have any idea how sintering is done(cost/ton,process parameters etc) because i have very less knowledge in this subject
The other info i have is density is 1.2-1.4g/cc (Apprx),
Di/Da -2 mm

Waiting for yr reply

To my knowledge these parts are made by coating over a sphere and burning out the sphere. Graphite might be an option for a sphere that can be sintered over in inert environment and then burned out in air.
