Description

technical field [0001] The invention belongs to the technical field of energy-saving materials, and in particular relates to an energy-saving honeycomb ceramic material and a preparation method thereof. Background technique [0002] As a renewable energy source with huge resource potential, solar energy plays a pivotal role in my country's clean energy strategy. Solar energy is a form of energy that is discontinuously distributed in time. To enable it to continuously supply energy to users, heat storage is an important link. At present, there are some shortcomings and deficiencies in most solar heat utilization thermal storage materials. [0003] Existing heat storage materials have limited heat storage density, single structure, small specific surface area, and low heat charge and discharge efficiency. [0004] Honeycomb ceramics are functional porous materials with high specific surface area and good physical and chemical stability, and are widely used in industrial fiel...
