摘要： PROBLEM TO BE SOLVED: To stably produce dense metal oxide film almost free from impurities by depositing powder on an electrode substrate by electrophoresis using metal powder produced by a sol-gel method as starting material, sintering and oxidizing the deposited powder by heating. SOLUTION: Compds. of metals such as Pb, La, Zr, Ti and Li are gelatinized in a soln. through a sol state and the soln. is concd. by heating or spray-dried to form an amorphous or crystal phase compsn. This dry product is pulverized and added to a solvent to prepare a soln. for deposition by electrophoresis and electric current is supplied between a Pt electrode 3 as the cathode and an alumina substrate 1 as the cathode in the soln. to electrodeposit metal powder on the substrate 1. The substrate 1 is then pulled up and the powder is sintered and oxidized by heating in air. The objective very dense nonporous metal oxide film almost free from impurities is stably produced. The metal oxide is, e.g. (Pb, La) (Zr, Ti)O3 .

摘要： PURPOSE: To prevent the deterioration of a heater base material and improve the durability thereof by restraining the evaporation or oxidation of the base material via the formation of a ceramic film thereon at a sintering process after the electrode-deposition of ceramic particles, using the electrophoresis method. CONSTITUTION: Ceramic particles are electro-deposited on a heater base material in water or nonaqueous solvent suspension, using the electrophoresis method and sintered at the preset temperature, thereby forming a ceramic film on the base material. As a result, a dense ceramic protection film of uniform thickness is formed on the base material over a wide range. In this case, the base material is preferably a kanthal, platinum alloy, molybdenum or tungsten filament. Also, alumina fine particles are used as the ceramic particles. Furthermore, the electro-deposition of ceramic particles is made at voltage between 1 and 35V over 0.5 to 15 minutes, and preferably the particles are sintered at a temperature between 1,500 and 1,650 deg.C.

摘要： PROBLEM TO BE SOLVED: To prevent the transparency of a deposit substrate from dropping, regarding non-aqueous suspensions in the deposit of a luminous material, particularly a phosphor, generated as a result of electrophoresis. SOLUTION: These suspensions are prepared so as to contain a polar organic solution obtained by mixing nitromethane and aliphatic alcohol, except for methyl alcohol, containing at least one metal salt and one vegetative protein in a solvent, and the powder of a luminous material deposited in the solution via the suspensions. The suspensions are used for the manufacture of a tricolor screen having conductor tracks 15 to 17 covered with the first color 18, the second color 19 and the third color 20, and the excitation of a phosphor is implemented via the means of an electron source having a micro chip 1c as well as a radiation cathode micro chip 1c.
