Abstract: A method for modifying a phase change ink jet head by applying a non-wetting material to the discharge surface is provided such that an ink contact angle between about 80.degree. and about 90.degree. is maintained on the discharge surface after continued exposure to molten phase change inks. Furthermore, the method provided ensures that the layer of non-wetting coating material does not chip or wear off during the normal operation of the ink jet printer. In this way, the ink jet printer is capable of accurate placement of phase change ink drops without increased surface wetting and off-axis shooting that traditionally occurs after continued use.

Abstract: A sintered body of tin oxide is made by forming a finely divided mixture containing at least about 0.2 weight percent ZnO, at least about 0.2 weight percent SiO.sub.2, up to about 0.5 weight percent Al.sub.2 O.sub.3, balance pure SnO.sub.2, with the sum of the proportions of ZnO and SiO.sub.2 being less than about 2 weight percent. The mixture is compacted and heated to a sintering temperature. The tin oxide may be doped with antimony.

Abstract: A sintered body of indium tin oxide is fabricated by forming a finely divided mixture of indium oxide, tin oxide, aluminum oxide and silicon dioxide, compacting the mixture, and heating the mixture to a sintering temperature.
