Abstract
Specifically identified products are produced using powder formed from particles of a naturally occurring organic oxide mineral with substantially no free silica, preferably nepheline syenite, where the powder is essentially dry with a moisture content of less than 0.8% and has a controlled maximum particle size with 99.9% of the particles of the powder having a particle size of less than 10 microns defined as “fine grain ultra-fine” powder, which fine grain ultra-fine powder is preferably less than 6 microns, and where the fine grain ultra-fine powder comprises 3-25% by weight of the identified product.
