1. the production method of an oxide matrix composition, described method comprises:

  • 1) mineral of at least one layering are decomposed or the remaining mineral constituent of generation that scales off fully;

    The mineral of wherein said layering are clay, clay mineral or the ion-exchange compound that layered crystal structure is arranged;

    2) described remaining mineral constituent is contacted with at least one oxide precursor compounds and produce the first mixture;

    Wherein said oxide precursor compounds is selected from silica source, alumina source, phosphate source or its mixture;

    3) pH of described the first mixture is adjusted in 4 to 9 scope to form gel or precipitation;

    With4) dry at the temperature in 150 to 800 ℃

    of scopes and the described gel of roasting or the described oxide matrix composition of precipitation generation.
