Solubility limit is the minimum concentration of solute that may be added without forming a new phase
- False
Solidus line normally represents the boundary between a liquid phase region and a two phase region
with the liquid [e.g, the boundary L/ (α+L) - False
Eutectic structure forms prior to the primary phase during cooling - FALSE
Non equilibrium cooling results in cored structure - TRUE
Eutectoid reaction is an incongruent transformation - TRUE
In ceramic materials, anions are positively charged metallic ions - False
The rock salt crystal structure in ceramics may be thought of as two interpenetrating BCC lattices, one
composed of cations, the other composed of anions, - False
Three primary polymorphic crystalline forms of silica are quartz, cristobalite, and tridymite - True
The boiling temperature of the hydrocarbons in the paraffin family decreases with increasing molecular
weight - False
Binary Isomorphous phase diagram contains - a eutectoid reaction
In alloy systems, equilibrium can be defined as - the state of a system corresponding to the maximum
free energy, where the phase characteristics remain constant over definite time periods
In the following reactions during equilibrium cooling (α,β,y stands for solid phases), which is a eutectic
reaction? - L -> α + β
