The structural changing in the binder in course of periclase-carbonaceous refractories oxidizing

Abstract

The investigating results are given for the binders structural changing in the periclase-carbonaceous refractories when their treating in the oxidizing environment. After
all carbon which binds the periclase grains burns down at 1000 °C the refractories compression strength measured at room temperature downed by 64 % but the refractory
product didn't fall apart. In this situation the inorganic chemical bonding fulfilled the function of the binder which consisted of highly-dispersed calcium silicate, of iron and of the solid solution of magnesia, calcium and iron oxides' fine fraction. The results obtained allow to predict more reliably the refractories properties changing in their service on base of their raw materials. Ill. 3. Ref. 5. Tab. 2.
