Beschreibung
Zusammenfassung:	A thixotropic ink for use in manufacturing a varistor comprising the following constituents:a) zinc oxide,b) ceramic structure influencing additives including bismuth oxide, boric acid, boron oxide, chromium oxide, cobalt oxide, magnesium oxide and tin oxide,c) a grain growth influencing additive selected from the group consisting of antimony oxide, silicon dioxide and titanium dioxide,d) an organic solvent carrier,e) an organic viscosity influencing additive, andf) an organic binder.The composition may serve as a ceramic ink for use in the manufacture of multilayer varistors, especially using a screen printing process.
