MAYENITE PRODUCTION METHOD

摘要

The present invention provides a production method of mayenite in which mayenite can be produced without requiring a high-temperature treatment, and the cost of equipment and heating cost are inexpensive, and in its turn, the production cost of mayenite is inexpensive. The production method of mayenite is characterized in that mayenite (Ca 12 Al 14 O 33 ) is formed by baking katoite [Ca 3 Al 2 (OH) 12 ]. A baking temperature of katoite is preferably from 300 to 500°C. In addition, it is preferable to use, as the katoite, a product generated by introducing aluminum and calcium hydroxide [Ca(OH) 2 ] into water and allowing them to react with water.
