he modified strontium titanate ceramic material of composition 0.91(SrTiO3)+0.09(Bi2O3·3TiO2) was prepared by sol-gel process using (C4H9O)4Ti, Sr(NO3)2,Bi(NO3)3 and (NH4)3(C6H5O7) as row materials through the formation of multi cetric-comp lexes as intermediate. The modified SrTiO3 condenser material was ultimately prepared by doped with 3mol%PbO, 3mol% Li2O and 0.4mol%Rb2O on above prepared material through mixing, pressing to pellet, drying and sintering procedures.Investigation of the electric properties of prepared condenser material shows that it has dielectric constant 2200(30℃) with a temperature coefficient< 2.5×10(-3) /℃ (-70 ̄70℃). a loss factor ig δ<0.004, a dc resistivity 2×1012Ω. cm(30℃) and break down voltage > 15000kV / m.This material is a good choice for the fabrication of high voltage ceramic capacitors.

The effect of the thermal conductivities of condenser materials on dropwise condensation heat transfer has not been resolved yet. Numerical simulation of dropwise condensation heat transfer of steam on copper, stainless steel, zinc, mild steel surfaces are performed in this paper by using a model of dropwise condensation heat transfer proposed by the present authors. The results indicate that dropwise condensation heat transfer coefficient is greatly dependent upon the surface thermal conductivity, and...

The effect of the thermal conductivities of condenser materials on dropwise condensation heat transfer has not been resolved yet. Numerical simulation of dropwise condensation heat transfer of steam on copper, stainless steel, zinc, mild steel surfaces are performed in this paper by using a model of dropwise condensation heat transfer proposed by the present authors. The results indicate that dropwise condensation heat transfer coefficient is greatly dependent upon the surface thermal conductivity, and decreases with decreasing surface thermal conductivity.
