Abstract
Izvršeno je ispitivanje utjecaja dodatka poli(vinil-alkohola) kao surfaktanta na veličinu i aglomeraciju čestica magnezijeva oksida dobivenog iz gorke morske vode. Proces taloženja magnezijeva hidroksida provodio se uz zasićenu vodu vapnenicu kao taložni reagens. Poli(vinil-alkohol) dodavao se u masenom omjeru (1:1,5) u odnosu na dobivenu masu magnezijeva hidroksida. Nakon procesa sušenja i kalcinacije uzorku kalciniranog magnezijeva oksida određena je raspodjela veličine čestica i kemijski sastav. Dobiveni rezultati pokazuju da dodatak surfaktanta pozitivno utječe na smanjenje veličine čestica, sprječava njihovo nakupljanje, ali ne sprječava potpuno stvaranje aglomerata. Dobiveni magnezijev oksid zatim je sinteriran pri temperaturama 1400°C, 1500°C i 1600°C uz vrijeme izotermnog zagrijavanja 2 sata. Iz dobivenih rezultata također se može uočiti da povećanje temperature sinteriranja ima pozitivan utjecaj na mikrostrukturu, gustoću, poroznost i smanjenje sadržaja bora u sinteriranim uzorcima magnezijeva oksida dobivenog iz gorke morske vode.
Abstract (english)
The influence of the addition of poly(vinyl ̶ alcohol) as a surfactant on the size and agglomeration of magnesium oxide particles obtained from seawater bittern was tested. The magnesium hydroxide precipitation process was carried out using saturated limestone water as precipitation reagent. Poly(vinyl ̶ alcohol) was added in a mass ratio (1:1,5) in proportion to the magnesium hydroxide mass obtained. After the drying and calcination process, the particle size distribution and chemical composition of the calcined magnesium oxide sample were determined. The results show that the addition of surfactants has a positive effect on the reduction of particle size and prevents their accumulation, but not the complete formation of agglomerates. The magnesium oxide obtained was then sintered at temperatures of 1400 °C, 1500 °C and 1600 °C with an isothermal heating time of 2 hours. The results obtained show that increasing the sintering temperature has a positive effect on the microstructure, density, porosity and reduction of boron content in the sintered magnesium oxide samples from seawater bittern.
