Description
この実施例は、カーボンブラックの蜂巣状の豆炭の調製を示す。カーボンブラック(45.4kg)、13.0kgの精製した糖、および6.5kgのアジピン酸を、55ガロン(約0.2立方メートル)の樹脂ライニング(plastic−lined)した鋼ドラム缶中で混合した。当該ドラム缶の内容物を、7時間、ドラム缶ローラーを使用して混合した。脱イオン水(47kg)を、当該混合物に加え、混合をさらに15時間続け、粘稠性のペーストを得た。
A120−KVA アーク電気炉(直径24インチ(約61センチ)のグラファイト炉、および直径6インチ(約15センチ)のグラファイト電極を備えている)に、石英塊(6.00kg)、2.78kgの木片、および2.48kgの実施例1の蜂巣状の豆炭を入れた。アークを打った約8時間後、当該炉の出銑穴を開け、ケイ素を取り出した。その後、約2時間おきに、全期間(60時間)の間、当該炉は出銑された。各出銑の後、当該炉を手作業でかき立て、原料、すなわち、豆炭、石英、および木片を、最初の充填の重量比で入れて、一定の充填深さを維持した。60時間の稼動の間、468kgの石英、171.1kgの蜂巣状の豆炭、および130.3kgの木片を当該炉に供給し、計124kgのケイ素(エネルギー消費は4249kwh)を生産した。稼動の最後の24時間の間、192kgの石英、77.4kgの蜂巣状の豆炭、および101.8kgの木片を当該炉に供給し、72.2kg(80.5%)のケイ素(固有のエネルギー消費は26.6kwh/kg Si)を生産した。当該ケイ素は、それぞれ平均4.2ppmwおよび47.9ppmw(グロー放電質量分析によって測定)のホウ素量およびリン量を有していた。
120−KVA アーク電気炉(直径24インチ(約61センチ)のグラファイト炉および直径6インチ(約15センチ)のグラファイト電極を備えている)に、6.00kgの石英塊および3.02kgの実施例1の蜂巣状の豆炭を入れた。アークを打った約9時間後、当該炉の出銑穴を開け、ケイ素を取り出した。その後、約2時間おきに、全期間(55時間)の間、当該炉は出銑された。各出銑の後、当該炉を手作業でかき立て、原料、すなわち、豆炭および石英を最初の充填の重量比で入れて、一定の充填深さを維持した。55時間の稼動の間、474kgの石英および232.2kgの蜂巣状の豆炭を当該炉の供給し、計131kgのケイ素(エネルギー消費は4073.1kwh)を生産した。稼動の最後の24時間の間、282kgの石英および142kgの蜂巣状の豆炭を当該炉に供給し、102.1kg(77.6%)のケイ素(固有のエネルギー消費は25.3kwh/kg Si)を生産した。当該ケイ素は、それぞれ平均2.8ppmwおよび16.7ppmw(グロー放電質量分析によって測定)のホウ素量およびリン量を有していた。
