1. Structural studies of niquel oxide xerogels. / Estudos estruturais de xerogéis de óxido de níquel.
Structural properties of several xerogels obtained by the sol-gel procedure and heat treated at different temperatures between 150 and 900ºC were studied. The initial systems were dry gels prepared from liquid solutions composed of nickel chloride, buthanol, water and acetic acid. During the different isothermal treatments, volatile species leave the inicia
