Abstract
Mέθοδος παραγωγής αλφα-ημιενύδρου θειικού ασβεστίου από λεπτώς διαμερισμένο θειικό ασβέστιο δι' ανακρυσταλλλώσεως του δισενύδρου θειικού ασβεστίου παρουσία κορεσμένου υδρατμού, όπου από το δισένυδρο θειικό ασβέστιο σχηματίζονται διαμορφωμένα σώματα, τα οποία διαθέτουν 15 έως 60% όγκο πόρων καθώς και εντός των πόρων περισσότερο από 5% κατ' όγκον αέρα (όλα τα εκατοστιαία δεδομένα υπολογιζόμενα επί του όγκου των μεμονωμένων διαμορφωμένων σωμάτων). Τα διαμορφωμένα σώματα οδηγούνται εντός αυτοκλείστου. Παρουσία ικανής ποσότητας ύδατος εντός των πόρων ελέγχονται η κρυσταλλική ανάπτυξη και το κρυσταλλικό φορτίο των κρυστάλλων αλφα-ημιενύδρου θειικού ασβεστίου, οι οποίοι αναπτύσσονται από υδατική φάση διαλύματος, μέσω θερμοκρασίας κατεργασίας εντός της περιοχής μεταξύ 110 βαθμούς κελσίου και 180 βαθμούς κελσίου καθώς και μέσω πιέσεως της ατμοσφαίρας κατεργασίας εντός του αυτοκλείστου. Τα διαμορφωμένα σώματα παραλαμβάνονται εκτός του αυτοκλείστου μετά την ανακρυστάλλωση και οδηγούνται στην χρησιμοποίηση. ω
