Definitions
- the present invention makes it possible to efficiently and easily form a carbonate having high crystallinity and orientation birefringence that is difficult to aggregate, especially a carbonate having any of a needle shape and a rod shape. And a method for producing a carbonate capable of controlling the particle size.
- inorganic fine particles usable for the crystal doping method are indispensable. It has been recognized that fine needle-like or rod-like carbonates can be used particularly preferably.
- the metal ion source is not particularly limited as long as it contains at least one metal ion selected from Sr + ions, Ca + ions, Ba + ions, Zn + ions, and Pb h ion force. It can be appropriately selected according to the conditions, and examples thereof include nitrates, chlorides, and hydroxides of at least one metal selected from Sr, Ca, Ba, Zn, and Pb.
- the carbon source is not particularly limited as long as it generates CO 2_ ions.
- the pH of the liquid (reaction liquid) after the completion of the heating reaction is preferably 8.20 or more. If the pH is lower than 8.20, coarse carbonates may be formed. Meanwhile, the P H is an on 8.20 or more, to be in the high alkaline range, fine carbonate salt is obtained.
- the heating reaction After completion of the measurement, the temperature at which the pH of the liquid is measured is room temperature, usually about 25 ° C.
- the liquid for reacting the metal ion source and the carbonic acid source preferably contains water. Therefore, the liquid for reacting the metal ion source and the carbonic acid source is preferably an aqueous solution or suspension.
- the liquid contains a solvent.
- the carbonate produced by the method for producing a carbonate of the present invention needs to have an aspect ratio of greater than 1, and preferably has a needle-like or rod-like shape.
- the aspect ratio represents the ratio between the length and the diameter of the carbonate, and the larger the value, the better.
- the carbonate produced by the method for producing a carbonate according to the present invention is highly crystalline, has a high agglomeration property, and is larger than the aspect ratio force. It is isotropic with little orientation inside the product, and is useful as a plastic reinforcement, friction material, heat insulator, filter, etc. In particular, in the case of a deformed composite material such as a stretched material, it is possible to improve the strength and the optical characteristics by orienting the particles.
