Applications:

Lithium tetraborate, also known as lithium pyroborate, has a molecular formula Li2B4O7 and a molecular weight of 169.12. High purity and high density lithium tetraborate is a new kind of temperature compensated surface wave substrate chip and piezoelectric single crystal substrate material, which has a wide and important application in microelectronics, digital technology, optoelectronic technology, new computer, video communication, military science and technology, aerospace, satellite communication, national defense technology and many other fields. For example, a lithium tetraborate piezoelectric crystal can be prepared, in particular, the preparation method relates to a large-size lithium tetraborate piezoelectric crystal. It includes pressing the synthesized lithium borate polycrystalline material into a dense cylindrical material block, loading the material block into a Pt crucible that has placed seed crystals in advance and putting it into the furnace.

The furnace temperature is controlled at 950~1000℃, the crucible decline rate is 0.1~0.6mm/h, and high-quality large single crystals with a thickness of 30~80mm, a width greater than 120mm and a length of more than 150mm can be grown. Then the large-size lithium tetraborate piezoelectric crystal profiles can be obtained by lateral machining, that is, along the large-size side as the axial direction of the crystal rod and the small-size side as the thickness direction of the crystal rod. Compared with the traditional declining method, the above method overcomes the technical bottlenecks such as difficult inoculation, easy leakage crucible and easy cracking of the crystal when growing large size lithium tetraborate crystal by the traditional declining method. The lateral growth and flat type crucible design can improve the crystal growth rate and reduce the difficulty of crystal growth, which is conducive to the realization of the industrial growth of large size lithium tetraborate crystal.

Overview:
Lithium tetraborate white crystal. Melting point 930℃. Slightly soluble in water, insoluble in ethanol and other organic solvents. Usually pentahydrate. Lithium pentaborate (Li2B10O16) is usually an octahydrate, a white powder with a relative density of 1.72, and loses all crystal water at 300-350 ° C. Both can be prepared by melting lithium hydroxide and boric acid together. Used as a enamel.
