Embodiment 1
[0016] A method for preparing ceramics capable of repeated heat storage, the specific steps are as follows:
[0017] Step 1): Weigh 10% trititanium pentoxide blue black powder and 90% pottery clay by weight percentage, mix the raw materials and inject them into a ball mill, add water and grind them, and the fineness of the ground slurry is required to be 300 mesh;
[0018] Step 2): Precipitate the ground mud material; take out the supernatant after sedimentation, take out the sediment and put it on the clean ground to dry in the sun, and the drying time is 90 days;
[0019] Step 3): put the dried soil into a mud mixer for mud refining, and remove the air in the mud at the same time;
[0020] Step 4): Make the refined mud into the corresponding green body, and dry it in a drying room at 100°C;
[0021] Step 5): put the dried green body into the fired ceramic green body, calcined at 800° C. for 10 hours, and naturally cooled to obtain a ceramic product that can store heat repea...
Embodiment 2
[0023] A method for preparing ceramics capable of repeated heat storage, the specific steps are as follows:
[0024] Step 1): Weigh 15% titanium pentoxide blue-black powder and 85% pottery clay by weight percentage, mix the raw materials and inject them into a ball mill, add water and grind them, and the fineness of the ground slurry is required to be 500 mesh;
[0025] Step 2): Precipitate the ground mud material; take out the supernatant after precipitation, take out the sediment and put it on a clean ground to dry in the sun, and the drying time is 60 days;
[0026] Step 3): put the dried soil into a mud mixer for mud refining, and remove the air in the mud at the same time;
[0027] Step 4): Make the refined mud into the corresponding green body, and dry it in a drying room at 80°C;
[0028] Step 5): put the dried green body into the fired ceramic green body, calcined at 1250° C. for 6 hours, and naturally cooled to obtain a ceramic product that can store heat repeatedly....
Embodiment 3
[0030] A method for preparing ceramics capable of repeated heat storage, the specific steps are as follows:
[0031] Step 1): Weigh 12% trititanium pentoxide blue black powder and 88% pottery clay by weight percentage, mix the raw materials and inject them into a ball mill, add water and grind them, and the fineness of the ground slurry is required to be 400 mesh;
[0032] Step 2): Precipitate the ground mud material; take out the supernatant after precipitation, take out the sediment and put it on the clean ground to dry, and the drying time is 75 days;
[0033] Step 3): put the dried soil into a mud mixer for mud refining, and remove the air in the mud at the same time;
[0034] Step 4): Make the refined mud into the corresponding green body, and dry it in a drying room at 90°C;
[0035] Step 5): put the dried green body into the fired ceramic green body, calcined at 1000° C. for 8 hours, and naturally cooled to obtain a ceramic product that can store heat repeatedly.
