Abstract

"The knowledge of the physical and chemical properties of refractories is of great importance in determining their usefulness and application. The thermal expansion of refractories is of particular importance in that it affects the thermal stability of the product. A high coefficient of thermal expansion leads to greater spalling and destruction of the bricks in use. It is, therefore, desirable to develop compositions having low coefficients of thermal expansion. This investigation was undertaken (1) to determine some of the properties of chromite-magnesite refractory mixtures in an attempt to determine the optimum composition of these mixtures, the specific properties including thermal expansion, absorption, firing shrinkage, and lattice dimensions of the spinel phase present, with special attention being given to thermal expansion-crystal lattice dimension relationship, and (2) to determine some of the properties of calcium aluminate cement-magnesite aggregate refractory castable compositions as a preliminary investigation into the usefulness of this castable, the specific properties, including: firing shrinkage, modulus of rupture, crushing strength, absorption, bulk density, thermal expansion, refractoriness under load, and mineral constitution"--Statement of Problem, page 5.
