Description
ナノ材料合成用独立型前駆体の製造
Mg約3.5重量%の不純物を含む平均粒度5μmの非晶質ホウ素粉末と、金属酸化物触媒として平均粒度が約40nmのFe2O3粉末とを混合して、混合粉末を製造した。以後、篩振動機(sieve shaker)を用いて、混合粉末を5分間均一に混合する工程を3回実施して、かたまった粉末を溶かして非晶質ホウ素粉末と金属触媒とを均一に混合して第1粉末を製造した。この時、第1粉末は約4gの非晶質ホウ素と約0.4gのFe2O3とを含ませた。
図8に示されたナノ材料合成装置を用いて、独立型前駆体からナノ材料であるBNNTを合成した。
図5および図6Cのように、直径が2mm(φ2)であり、10mmの間隔(d1、d1’)で離隔した複数の貫通ホールを形成したことを除き、実施例1と同様の方法でナノ材料合成用独立型前駆体を製造し、ナノ材料(BNNT)を合成した。
ナノ材料合成用前駆体粉末の製造
実施例1と同様の方法で第1粉末および第2粉末を製造した。実施例1と同一のバインダー粉末と発泡剤を用意し、第2粉末、バインダー粉末、および発泡剤を約1:2.5:0.2の重量比で混合してナノ材料合成用前駆体粉末を製造した。
製造されたナノ材料合成用前駆体粉末を、長さ7cm、幅1.5cm、深さ1cm規格のるつぼに1gを入れて均一に広げた後、図8に示されたナノ材料合成装置の反応ゾーンの中心にローディングした。以後、るつぼに広げられたナノ材料合成用前駆体粉末を用いて、ナノ材料であるBNNTを1日1回バッチ(batch)方式で合成した。
ナノ材料合成用ディスク状前駆体の製造(反応モジュール据え置き形態)
実施例1と同様の方法で第1粉末および第2粉末を製造した。実施例1と同一のバインダー粉末と発泡剤を用意し、第2粉末、バインダー粉末、および発泡剤を約1:2.5:0.2の重量比で混合してナノ材料合成用前駆体分散液を製造した。
ディスク状前駆体が据え置かれた反応モジュールを図8に示されたナノ材料合成装置に連続投入-吐出して、ナノ材料であるBNNTを合成した。
