Abstract
Magnesia pellets are formed from finely-divided, highly reactive, lightburned magnesia (MgO) particles by granulating such powders in conventional equipment using either an organic liquid or an organic liquid-binder mixture. The organic liquid may be an alcohol or a ketone the alkyl groups of which, independently, can have from 1 to 4 carbon atoms. Magnesium chloride and water are among disclosed binders which may be used in combination with said organic liquid. The organic liquid should be more than about 80% of any admixtures with water.
