HARDENABLE INORGANIC COMPOSITION GOOD IN LOW-LUMINOSITY COLORATION, AND COLORED INORGANIC HARDENED BODY

摘要

PROBLEM TO BE SOLVED: To provide a hardenable inorganic composition which utilizes the characteristics of meta-kaolin produced from Indonesian or Chinese kaolin having a less TiO₂ content of ≤1.3 wt.%, is prepared by blending the above kaolin and an alkali metal silicate in water and is good in low-luminosity coloration, and also to provide a low-luminosity colored inorganic hardened body produced by using the above composition and excellent in economical efficiency.;SOLUTION: The hardenable inorganic composition is prepared by blending 1-300 pts.wt. alkali metal silicate and 10-500 pts.wt. water based on 100 pts.wt. meta-kaolin having the TiO₂ content of ≤1.3 wt.%.;COPYRIGHT: (C)2007,JPO&INPIT
