Answer questions that your are 100% sure of...Thanks :D
The binary phase diagram has no eutectic isotherm line when eutectic isotherm line is continuous. eutectic isotherm line does not exist. cooling rate is very slow. components are completely soluble in one another at any proportions. In the solidification process in a eutectic system the primary a phase is formed in the region of single solid phase alpha. solid phases alpha + beta below the eutectic isotherm line. solid phase a and liquid phase L region between the liquids and the eutectic isotherm line. single solid phase beta. Crystal structures and properties of ceramic materials are generally influenced by: The magnitude of electrical charges of Cautions and Anions. The relative size of Cautions and Anions. The number of Anions surrounding the central Caution. Both (a) and (b) In ironically bonded ceramics, (1) Cautions and (2) Anions are respectively defined as: Metallic ions and positively charged (2) non-metallic ions and negatively charged. Non-metallic ions and negatively charged (2) Metallic ions and positively charged. Both Caution and Anions are non-metallic ions. None of the above.Explanation / Answer
Q8:
Ans: d
Reason: If the components are completely soluble at any proportion, ther wont be any isotherm. exmale: water + alcohol.
Q9:
Ans: c
Reason: First a mix of solid and liquid will be formed, than it will be totally solid.
Q10:
Ans: d
Reason: the charge and size will determine the strength and stability of the crystal.
Q 11:
ans: a:
In most of the ionically bonded ceramics, metals are cations and nonmetals are anaions.
