Embodiment 1
[0028] (1) the fused magnesia powder and the heavy sodium carbonate with a particle diameter of 60 μm are uniformly mixed to form the first mixture;
[0029] (2) The first mixture is mixed with barium carbonate and sodium silicate to form the second mixture. The mass ratio of fused magnesium oxide powder, heavy sodium carbonate, barium carbonate and sodium silicate is 40:50:6 :0.5;
[0030] (3) Based on the mass of the second mixture, add 12% water to the second mixture, stir and knead for 10 minutes and pass through a 20-mesh sieve to form a mixture;
[0031] (4) Compress the above-mentioned kneaded material at 16Mpa for a holding time of 30s; then dry at 25°C for 4h;
[0032] (5) Sintering at 835° C. for 1 hour to obtain a high temperature phase change heat storage brick.
