BURNED PRODUCT CONTAINING ANORTHITE
PROBLEM TO BE SOLVED: To provide a method for suppressing the production rate of an amorphous phase at a low level when obtaining a burned product containing coal ash from waste as a raw material as a main component and anorthite (CaAlSiO).SOLUTION: There is provided a burned product manufactured by burning a raw material having a residue after ignition at 950°C containing CaO of 20 to 45 mass%, AlOof 10 to 30 mass% and SiOof 35 to 55 mass% at 1000 to 1400°C and containing anorthite of 20 to 70 mass%, wollastonite of 5 to 35 mass% and having the content of an amorphous phase of 20 mass% or less.
【課題】廃棄物を原材料とする石炭灰を主成分としてアノーサイト（ＣａＡｌ２Ｓｉ２Ｏ８）を含有する焼成物を得るに際して、非晶質相の生成割合を低く抑える方法の提供。【解決手段】９５０℃での強熱後の残分が、ＣａＯが２０〜４５質量％、Ａｌ２Ｏ３が１０〜３０質量％、ＳｉＯ２が３５〜５５質量％の範囲内にある原料を１０００〜１４００℃で焼成し、アノーサイトを２０〜７０質量％、ウォラストナイトを５〜３５質量％含み、且つ非晶質相含有量が２０質量％以下である焼成物。【選択図】なし
