TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The antimony oxide comprises at least one selected from Sb2O3, Sb2O4 and Sb2O5. It takes the form of spherical powders. The organic vehicle comprises an acrylic or cellulose binder resin. It comprises at least one solvent selected from hexane, toluene, ethyl cellosolve, cyclohexanone, butyl cellosolve, butyl carbitol (diethylene glycol monobutyl ether), dibutyl carbitol (diethylene glycol dibutyl ether), butyl carbitol acetate (diethylene glycol monobutyl ether acetate), propylene glycol monomethyl ether, hexane glycol, terpineol, methylethylketone, benzylalcohol, gamma-butyrolactone, and ethyl lactate. The aluminum paste further comprises a glass frit. The glass frit comprises at least one selected from zinc oxide-silicon oxide (ZnO-SiO2), zinc oxide-boron oxide-silicon oxide (ZnO-B2O3-SiO2), zinc oxide-boron oxide-silicon oxide-aluminum oxide (ZnO-B2O3-SiO2-Al2O3), bismuth oxide-silicon oxide (Bi2O3-SiO2), bismuth oxide-boron oxide-silicon oxide (Bi2O3-B2O3-SiO2), bismuth oxide-boron oxide-silicon oxide-aluminum oxide (Bi2O3-B2O3-SiO2-Al2O3), bismuth oxide-zinc oxide-boron oxide-silicon oxide (Bi2O3-ZnO-B2O3-SiO2), and bismuth oxide-zinc oxide-boron oxide-silicon oxide-aluminum oxide (Bi2O3-ZnO-B2O3-SiO2-Al2O3) glass frits. The aluminum paste also comprises a dispersant, where the dispersant is at least one selected from stearic acid, palmitic acid, myristic acid, oleic acid, and lauric acid. Preferred Parameters: The antimony oxide comprises antimony oxide powders having an average particle size of greater than or equal to 0.01 to less than or equal to 10 mu m. The aluminum powders have an average particle size of greater than or equal to 0.1 to less than or equal to 10 mu m. Preferred Composition: The aluminum powders are present in an amount of greater than or equal to 60 to less than or equal to 80 wt.% based on the total weight of the paste. The organic vehicle is present in an amount of greater than or equal to 0.1 to less than or equal to 40 wt.% based on the total weight of the paste. The glass frit is present in an amount of greater than or equal to 0.01 to less than or equal to 20 wt.% based on the total weight of the paste.
