Sažetak
The effect of pH of the rinsing agent on the content of the B_2O_3, CaO and MgO in calcined magnesium oxide obtained from seawater by substoichiometric precipitation (were precipitation of magnesium hydroxide took place with 80 percentage of the stoichiometric quantity of the dolomite lime) has been investigated. The purpose of the study has been to ensure high purity magnesium oxide, particularly regarding the B_2O_3 content, because boron causes a problem in refractory magnesia for specialized refractory applications where high hot-strength is required. It has been established that the content of B_2O_3 in magnesium oxide samples is significantly reduced when the pH value of the agent used for rinsing the magnesium hydroxide precipitate increases.
