This invention provides a method for making Tl-Ca-Ba-Cu-O superconductive materials in a film shape. After placing a Ca2Ba2Cu3O7 powder onto some suitable substrate, such as platinum or copper, the substrate and powder are rolled between two rollers until a desired thickness is achieved. The film can then be taken off the substrate. Thallium oxide is then evaporated on the precursor film to make superconductive films. The Tl2O3 can be evaporated in a furnace or vacuum.

Uvumbuzi huu hutoa njia ya kufanya Tl-Ca-Ba-Cu-O vifaa superconductive katika sura ya filamu. Baada ya kuweka Ca2Ba2Cu3O7 poda juu ya baadhi ya substrate yanafaa, kama vile platinamu au shaba, substrate na poda ni rolled kati ya rollers mbili mpaka ununuzi unatarajiwa ni mafanikio. Kisha filamu inaweza kuondolewa kwenye substrate. Kisha oksidi ya thallium huyeyushwa kwenye filamu ya awali ili kutengeneza filamu za superconductive. Tl2O3 inaweza evaporated katika tanuru au utupu. Uhandisi wa umeme; Fizikia US5096881; AU650005 (B2) Chuo Kikuu cha Arkansas (Little Rock, AR) Shams, Q. A., Hermann, A. M., na Sheng, Z.
