  • Ma-M2T spinel solid solution enhanced magnesium oxide-based ceramic foam filter and preparation method therefor
    Patent number: 11529577
    Abstract: An MA-M2T spinel solid solution-reinforced magnesium oxide-based ceramic foam filter and a preparation therefor. The preparation method comprising: 1) preparing a ceramic slurry having a solid content of 60%-70% by dosing 15%-25% by mass of a nanometer alumina sol, 0.8%-1.5% by mass of a rheological agent, and the balance magnesium oxide ceramic powder comprising a nanometer titanium oxide sintering aid, and then adding deionized water and ball milling to mix until uniform, and then vacuum degassing the mixture; 2) soaking a polyurethane foam plastic template into the ceramic slurry, squeezing by a roller press the polyurethane foam plastic template to remove redundant slurry therein to make a biscuit, and drying the biscuit by heating it to 80° C.-120° C.; 3) putting the dried biscuit into a sintering furnace, elevating the temperature to 1400° C.-1600° C. and performing a high temperature sintering, cooling to the room temperature with the furnace to obtain the magnesium oxide-based ceramic foam filter.
