Summary: | The present invention relates to a new basic aluminum magnesium carbonate of the formula (I): Al2Mg4(OH)12CO3.3H2O and rhombohedral crystallization, whose reticular parameters are a=b=3,046 .ANG.; c=22.79 .ANG.; .alpha.=.beta.=90~; .gamma.=120~ and cell volume = 183 A3, whose X-ray diffraction spectrum shows the following d(.ANG.) values: 7.597; 3.798; 2.6202; 2.5698; 2.5322; 2.2830; 1.93545; 1.72447; 1.62930; 1.52289; 1.49318; 1.46002; 1.41351; 1.38528 and 1.31011; whose infrared spectrum shows characteristic bands at 1361 and 449 cm1 (Figure 1) and whose differential scanning calorimetry (DSC) is illustrated in Figure 2. This compound is used in therapeutics as an antacid and gastroprotector. |
