Description
本発明においては、火山灰と廃ガラス合計重量に対し14%〜43%(重量で、火山灰:廃ガラス=6:1〜4:3)となる廃ガラスを配合することによって、火山灰の70重量%を占める火山ガラス(耐熱性を有するアルミノ珪酸塩ガラス)の溶融温度を1200℃から750℃〜1100℃の温度域に降下させ得る。これによって、配合原料の加熱・焼結が容易となり低コスト化に資する。発明者の実験を伴う研究結果では、重量で、火山灰:廃ガラス=5:2(71.4%:28.6%)で最も良好な結果が得られた。
1)上記多孔質セラミック750gを水槽中に入れた。
2)模擬汚水とすべく、超純水15リットルを入れた水槽中に牛乳100ミリリットル、活性汚泥15ミリリットルを加えた。
3)水を循環させ、15日間試験を行った。
4)定期的に、COD値とBOD値を測定した。
Claims (3)
- 火山灰:廃ガラス=6:1〜4:3の配合比率(重量比)からなり粒径が数μmの微粉末の部分的溶融物からなる表面に開口をもつ10nm〜数10μmの孔径の連続細孔(トンネル構造)を有することを特徴とする多孔質セラミック。
- 火山灰:廃ガラス=6:1〜4:3の配合比率(重量比)の原料を粒径が数μm以下となるまで微粉砕し、混合、均質化した後、坩堝やステンレス鋼製の容器に収納して容器に蓋をし、然る後空気中800℃〜1000℃で30分間〜90分間加熱して容器中の原料を部分的に溶融した後加熱を止め、放冷することを特徴とする火山灰を原料とする多孔質セラミックの製造方法。
- 火山灰:廃ガラス=6:1〜4:3の配合比率(重量比)の原料に該原料の5%〜10%の炭素質材を加えて原料および炭素質材の粒径が数μm以下となるまで微粉砕し、混合、均質化した後、坩堝やステンレス鋼製の容器に収納して容器に蓋をし、然る後空気中800℃〜1000℃で30分間〜90分間加熱して容器中の原料を部分的に溶融した後加熱を止め、放冷することを特徴とする火山灰を原料とする多孔質セラミックの製造方法。
