METHOD FOR SYNTHESIZING MINERAL, APPARATUS FOR SYNTHESIZING SYNTHETIC MINERAL AND MINERAL, AND COAL ASH FOR SYNTHESIZING MINERAL AND ITS PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for synthesizing a boron-containing cyclic silicate mineral which can be industrially synthesized, a synthetic mineral and its synthesizing apparatus, and coal ash for synthesizing mineral and its processing method.;SOLUTION: The synthetic mineral contains two or more kinds of elements selected from silicon, boron, lithium, sodium, magnesium, aluminum, potassium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper and zinc and contains calcium of 5 wt% or less in terms of a metal and consists of the boron-containing cyclic silicate mineral. The boron-containing cyclic silicate mineral is synthesized by the method that it is synthesized by a hydrothermal reaction at a high temperature and pressure using the above raw material which contains the elements. The calcium content in the raw material can be 5 wt% or less.;COPYRIGHT: (C)2004,JPO
