Re: [GreenYes] Re: industrial low thermal expansion waste



Bob,

Semiconductor manufacturers are sources of aluminum oxide. Ideally, it ends up as product, but due to product standards, there's often high quality material remaining.

On the foundry sand, my understanding is that it generally comes out of the process pretty clean, but you might test for residual binder (used to make the mold to hold the liquid metal) which can contain furans. Different casting processes use different binders.

Hey Bob, GreenYessers,


Could used foundry sand fit that description and/or need?

Does anyone know of an waste industrial source for a low thermal expansion material?

Possibilities might include amorphous or vitreous silica or aluminum
oxide.

Granular consistency is preferred, but fines are a possibility.
