Zusammenfassung:A process for the preparation of active magnesium oxide having a large specific area by dispersing magnesium hydroxide or oxide with water forming a turbid liquid having a turbidity density of about 5 to 20 percent and vigorously agitating the liquid for about 5 to 60 minutes, the temperature of the turbid liquid being kept at about 80 DEG to 110 DEG C throughout the process, by introducing steam, washing the filter cake, drying and calcining the separated magnesium compound to obtain large surface area magnesium oxide.
