Calcium hydroxide and its varied applications


Calcium hydroxide or slaked lime and the specific products derived from it are of great benefit, it is reliable and especially effective for applications such as accelerating the kinetics of reactions, increasing the efficiency of absorption and guaranteeing a high degree of capture of gaseous pollutants. Moreover, a correct combination of the above-mentioned parameters of calcium hydroxide means that highly reactive products can be offered.

The different types of crystallization of the PCC and its practical applications


The production of the PCC is adapted to the needs of the client, since according to the size, the shape of the particles obtained, the distribution of the size of the crystals, and the surface area, different properties are obtained.
