Description

technical field [0001] The invention belongs to the technical field of new materials and functional materials, and in particular relates to a preparation method of lithium metatitanate for tritium multiplication ceramic materials. Background technique [0002] With the rapid development of the global economy, human beings have an increasing demand for energy, and the original resources left by the earth to human beings are getting less and less. The problems of energy shortage and deteriorating environment have become common difficulties for all mankind. Therefore, seeking cleaner, safer and renewable energy has attracted much attention and has become the consensus of people in all countries. [0003] Thermonuclear fusion is one of the most important energy research directions at present, and materials for producing tritium by fusion neutrons are particularly important. Lithium metatitanate (Li 2 TiO 3 ) is one of the most promising materials for use as lithium-based cera...
