PURPOSE:To improve the discharge characteristic by forming LaB6 cathode with LaB6 powder thermally processed under inert gas ambient after atomization. CONSTITUTION:LaB6 is atomized into fine powder then cleaned with pure water to remove impurity. Then it is thermally treated under inert gas ambient such as N2 or foaming gas under the temperature of 1,000-1,500 deg.C, for about 1-2hr. Consequently, impurities are removed from the surface of micro particle of LaB6 while the surface area is reduced to achieve stabilization. Then thermally processed LaB6 is employed to form LaB6 cathode through thick film printing method or electrodeposition resulting in improvement of burning phenomena of display pattern and reduction of aging of display quality. |
