The present invention refers to a microporous rystalline material of zeolitic nature named ITQ-10, to the process of its preparation and to the use of ITQ-10 in processes of separation and transformation of organic compounds. In calcinated and anhydrous state, the composition of the material ITO-10 corresponds to the empirical formula <paragraph lvl="0"><in-line-formula>x(M1/nXO2):yYO2:SiO2 </in-line-formula>wherein x has a value lower than 0.1 whereby it may be equal to zero; y has a value lower than 0.1 and may as well be equal to zero; M is H+ or an inorganic cation of a charge +n; X is a chemical element with oxidation state +3 (as for example Al, Ga, B, Cr) and Y is a chemical element with oxidation state +4 (as for example Ti, Ge, V). When x=0 and y=0, the ITQ-10 material may be described as a new polymorphous form of silica of microporous character. The zeolitic material of this invention is also characterized by its characteristic X-ray diffraction pattern and its microporous properties. The preparation process is characterized by the use of one or several organic additives in a reaction mixture which is made to crystallize by means of heating.
