Abstract
Inventia se refera la un procedeu hidrotermal de obtinere a hematiei, care se caracterizeaza prin aceea ca folosindu-se o suspensie apoasa de oxi-hidroxid feric, constituita din 4,5 parti greutate oxi-hidroxid feric, d-FeO(OH) si 4 parti greutate apa, suspensia apoasa este înclalzita pîna la temperatura de reactie de 210 plus minus 5 degree C, cu o viteza de încalzire de 3 degree C/min, mentinîndu-se timp de 2 h la aceeasi temperatura, dupa care suspensia este spalata si filtrata si apoi produsul obtinut se usuca la 110 degree C.
