Abstract： |
The invention relates to a hydrothermal synthesis manufacturing method for magnesium borate crystal whisker that adopts inorganic magnesium salt, magnesium borate and inorganic alkali as main raw material, adding inorganic alkali into mixture solution of magnesium salt and borate at 10-90 degree centigrade, taking hydrothermal treatment to normal temperature product at 100-300 degree centigrade, realizing directional growth through controlling hydrothermal rocks constituents and technology condition to gain one dimension appearance feather alkali magnesium borate crystal whisker, washing, drying the hydrothermal product, and baking under the existence of crystallographic form transforming agent at 600-800 degree centigrade to realize structure reconstruction and phase converting to gain regular appearance and equal size magnesium borate crystal whisker. The invention has the advantages of simple technology, mild condition, cheap raw material, and easy to be manufactured. |
