The Influences and the Mechanism of Action of Grinding

In this paper, the effect of citric acid on the hematite was studied and the mechanism was analyzed. The results indicated that under the condition of the optimal grinding medium, compared with the result without citric acid added, with citric acid added at the mass of 0.10% of the hematite, the content of-0.074mm of grinding production was increased by 7.11%; physical adsorption and chemical ...

Synthesis of chemically bonded porous ceramics from

2021-10-22  Conclusions. In the present study, MgO-based chemically bonded porous ceramics from used MgO–C refractory bricks (MgW) were obtained by acid-base reactions. The increase in the KDP/MgW mass ratio (0.18–0.33) increased the total porosity of the samples, although the compressive strength was statistically the same.
