Beschreibung
Zusammenfassung:	The present invention relates to calcium hydroxide particles having a total pore volume of greater than 0.18 cm³/g, said total pore volume being calculated according to the BJH method for a range of pores having a diameter of between 20 and 1000 Å, said particles being characterized in that the BJH partial pore volume for the range of pores having a diameter of between 20 and 100 Å corresponds to more than 20% of said BJH total pore volume. La présente invention se rapporte à des particules d'hydroxyde de calcium présentant un volume poreux total supérieur à 0,18cm³/g, ledit volume poreux total étant calculé selon la méthode BJH pour une gamme de pores ayant un diamètre compris entre 20 et 1000 Å, lesdites particules étant caractérisées en ce que le volume poreux partiel BJH pour la gamme de pores ayant un diamètre compris entre 20 et 100 Å correspond à plus de 20% dudit volume poreux total BJH.
