Mehanohemijsko-termički postupak dobijanja maskirnog pigmenta

Abstract

U ovom radu je ispitivana mogućnost dobijanja maskirnog pigmenta mehanohemijsko termičkim postupkom kao i energetsko učešće mehanohemijskog tretmana u dobijanju maskirnog pigmenta stehiometrijske formule Co0,51Zn0,29Mg0,41Cr1,24Al0,24Ti0,31O4. Mehanohemijski i termički tretirani uzorci smeše oksida radi dobijanja kompleksnog spinela su eksperimentalno istraživani u više serija opita, pri čemu su menjani parametri vezani za rad visokoenergetskog vibracionog mehanoaktivatora. Mehanohemijskom aktivacijom smeše oksida (Cr2O3, CO-oksida, ZnO, TiO2, MgO i Al2O3), u vibracionom mehanoaktivatoru sa prstenovima od 30; 60 i 90 min, a zatim termičkim tretiranjem u elektrootpornoj peći, pri vremenu zadržavanja uzorka od 1h, dobija se materijal spinelne strukture koji je pogodan kao maskirni pigment u vojnoj industriji.

In this paper the possibility of obtaining masking pigment mechanochemically thermal process and the energy share of mechanochemical treatment in obtaining masking pigment by stoichiometric formula (Co 0.51 Zn 0.29 Mg 0.41 Cr 1.24 Al 0.24 Ti 0, 31 O 4). Mechanochemical and heat treated samples to obtain a mixture oxide spinel complex were experimentally investigated in a series of experiments wherein the altered parameters related to the operation of high energy vibratory mechanoactivator. Mechanochemical activation mixture oxide (Cr2O 3, C-O oxide, ZnO, TiO 2, MgO and Al 2 O 3), in vibration mechanoactivator with rings of 30; 60 and 90 min, and then, heat treatment in an electric furnace, with the sample retention time of 1 hour, the material is obtained, which spinel structure is suitable as the pigment in the masking military industry.
