A transparent ceramic structure and a method of surface treatment thereof are disclosed. A glass powder is applied over an unpolished surface of an intrinsically transparent ceramic structure. The ceramic structure is then placed in high temperature which is higher than the melting temperature of the glass powder and lower than 1,700 ° C. for about 1 minute to about 5 minutes. The transparent ceramic structure is removed from the environment and cooled down so as to obtain the desired transparency and strength of the ceramic structure.

Abstract:
A method for producing a positive electrode material adapted to the Li-ion secondary batteries is disclosed. The produced material has the following formula (I), Li1+xMn2−yMyO4 (I) wherein M is Mg, Al, Cr, Fe, Co, or Ni; 0≦x≦0.4, and 0≦y≦0.2. The method is achieved by co-precipitating a gel salts with an organic acid. First, salts of Li, Mn and M are mixed with at least a solvent to form an initial solution. The mole ratio of Li, Mn and M ions in their respective salts is (1+x):(2−y):y. Next, at least a chelate is added into the initial solution to form a suspension, which is then filtered to obtain a co-precipitate. Finally, the co-precipitate is calcined and heated to obtain the final product.
