Abstract The frites by mole fraction of 2.5 SiO2, 0.20 Al2O3, 0.15 B2O3, 0.15ZnO, 0.17K2O, 0.67CaO systems in three ratios of S including 0.37(denoted by F1frites ),0.31(F2), 0.24(F3) (S=K2O/CaO+ZnO) were studied. ZnO powder with 500 nm (N series) and >1μm sizes (F series) opted from the recycled Zn ingots dusts and commercially ZnO respectively, were used as the raw materials. By decreasing the S ratio, the Molar Volumes of frites were decreased, The glass transition ΔTg(=-154ºC), and the crystallization temperatures ΔTp (=+17ºC) values were decreased and increased respectively. It was shown that the GS (glass stability) values are independent of the Zinc Oxide's powder size, while the Molar Volumes of N series were lower than the F ones. The Zinc Silicate (Willemite) beside Anorthite and Parawollastonite phases were crystallized in the resulted glazes. The hardness values were in 700-850 Hv range, the transparency and whiteness were higher than 80 and 60 respectively.

The dependence of the induction period of crystallization on supercooling was examined for the silver nitrate-ethylene glycol system over the concentration region of silver nitrate lome fraction of 0 to 0.12. Addition of AgNO3 to ethylene glycol was found to increase considerably the critical induction period of crystallization, although to a lesser extent than Ca(NO3)2, CaCl2, ZnCl2, LiCl and LiNO3 do. The effect of these salts on the critical induction period of crystallization in dimethylsulfoxide, dimethylformamide, dimethylacetamide and methanol was compared in terms of the solvent-rich composition limit of the glass-forming ability. By using the TTT(Time-Temperature-Transformation) theory, it has been deduced that the effect of the salts on the critical induction period of crystallization of ethylene glycol is probably due to the different dependences of viscosity on their concentration in ethylene glyco in the supercooling region.
