Embodiment 1
[0030] This embodiment provides a simple and efficient method for preparing a low thermal conductivity MgO-CoO solid solution pressure transmission medium, including the following steps:
[0031] (1) First according to the mass ratio M MgO :M CoO = 2: 1 ratio mixes the two initial powders, then puts the two initial powders into a mixing tank filled with absolute ethanol, and then places the mixing tank with the materials on the mixer for continuous Mix the materials for 5 hours, then pour the mixed slurry into a stainless steel square pan, and finally place it in a dry and ventilated place for continuous drying for 10 hours;
[0032] (2) Break the massive precipitate obtained after drying into small pieces with a grinding rod, then grind it with a mortar, and then sieve it with a mesh sieve, and then continue to grind the powder that has not passed the sieve until it is The particle size is 0.3μm;
[0033] (3) First put the ground and sieved powder into the corundum ark, ...
