[0020]Example 1
[0021]A high storage density solar energy energy storage ceramic material consists of 69 parts of the silicon nitride, 37 boron nitride, 21 parts of carbide, 11.5 parts of silicide, 8.7 parts of alumina, sodium silicate. 4.5 parts, 5.4 parts of magnesium oxide and 3.2 coplastium oxide.
[0022]Each of the components is a powder having an average particle diameter of 10-50 nm.
[0023]The preparation method of the solar energy storage ceramic material includes the following steps:
[0024](1) Weigh all the components, mix, ball mills, and wear materials.
[0025](2) Mix the slurry in step (1) and the primer polyurethane foam in accordance with the weight ratio of 1:25 and stirred for 25 minutes, and then the ultrasound treatment is mixed well and uniform, and pre-press forms a strip blank;
[0026](3) Place the strip blank obtained by step (2) under 135 MPa conditions, and then dried in vacuo to obtain a blank;
[0027](4) Put the blank after step (3) is placed in a vacuum hot pressing ...
