1. A process for producing a ceramic material, comprising the following steps:
(a) solubilizing 23 to 360 g of alkali carbonate in 500 to 1,000 mL of water, wherein the alkali carbonate is Na2CO3, K2CO3, or a combination thereof;
(b) adding 200 to 800 g of alkaline earth metal oxide or hydroxide;
(c) adding a binding agent to form a mixture;
(d) homogenizing the mixture obtained in step (c) for 5 to 30 minutes to form a clay;
(e) removing, and optionally molding the clay obtained in step (d) for 1 to 3 hours;
(f) drying the clay at a temperature from 50° C. to 150° C., preferably 80° C., for a period of 3 to 48 hours.
