ポリエチレンライニングボールミルジャーに、100グラム(g)の脱イオン水、0.5gのクエン酸アンモニウム分散剤、400gの様々な酸化アルミニウム粉末(表1で報告されており、表2には原料の供給源を報告している)を投入した。約700グラムのアルミナ粉砕媒体(直径:10mm、99.9%アルミナ、Union Process,Akron,Ohioから入手)をボトルに加え、混合物を120rpmで24時間粉砕した。粉砕後、粉砕媒体を取り除き、デシケータージャー中に載置し、機械式ポンプを使用して真空にかけて(真空下で約10分間保持)スラリーを脱気した。生じたスラリーを、約0.4mmの側長、0.1mmの深さを有する切頭三角錐の複製パターンを含み、5重量%のエタノール溶液から乾燥して残留した鉱油の局所コーティングを有するポリエチレンシートに注入した。スキージを使用して、スラリーをシートの約400cm2の領域に広げて被覆させた。次に、セラミックスラリーを含有するシートをヒートガンで乾燥させた。乾燥後、シートを激しく振って、その時には切頭三角錐の形状になっていた生じた成形研磨材前駆体粒子を取り除いた。
約17グラムの生じた成形研磨材粒子を研磨布紙ディスクに組み込んだ。従来の手順にしたがって研磨布紙ディスクを作製した。成形研磨材粒子を、従来の炭酸カルシウムを充填したフェノール性のメイクレジン(make resin)(48%のレゾール型樹脂及び52%の炭酸カルシウムを水及びグリコールエーテルで81%固体分に希釈したもの)、及び従来のクライオライトを充填したフェノール性のサイズレジン(size resin)(32%のレゾール型樹脂、2%の酸化鉄、66%のクライオライトを水及びグリコールエーテルで78%固体分に希釈したもの)を使用して17.8cmの直径及び0.8mm厚のバルカンファイバー裏材(直径2.2cmの中央穴を有する)に結合した。湿ったメイクレジンの重量は、約185g/m2であった。メイクコートを適用した直後、成形研磨材粒子を静電塗装した。メイクレジンを120分間88℃で加熱した。次に、メイクコート及び研磨材粒子にクライオライトを充填したフェノール性のサイズコートをコーティングした。湿ったサイズの重量は、約850g/m2であった。サイズレジンを12時間99℃で加熱した。研磨布紙ディスクを試験前に屈曲させた。
手順を数回繰り返して、より大量の材料を生成する以外は、実施例2に記載されるようにして、実施例8a〜8eの成形研磨材粒子を調製した。続けて、焼成された成形粒子を結晶粒成長させ、室温から最高着火温度(表4で報告)までにおける25℃/分の傾斜率を含む熱処理を誘導する。実施例8a〜8eの材料は、熱処理に使用される最高着火温度が異なる。
低温で様々な焼成添加剤を導入して緻密化を促進する以外は、実施例1に記載されるようにして実施例9〜13を調製した。焼成添加剤及び96%の理論密度を達成するのに必要な最低着火温度を以下の表5にまとめた。
テフロンライニングアトライターミルジャーに、250gの脱イオン水、4gの硝酸(70%濃縮)、190gの水酸化アルミニウムSH−20(Dadco Aluminium and Chemicals,Lausanne,Switzerlandから入手)を投入した。この粉末は、約0.25重量%のNa2Oを含有していた。約700グラムのアルミナ粉砕媒体(直径:5mm、99.9%アルミナ、Union Processから入手)をジャーに加え、混合物を500rpmで24時間粉砕した。粉砕後、粉砕媒体を取り除き、デシケータージャー中に載置し、31gの硝酸マグネシウム水酸化物(Mg(NO3)2・6H2O)(Sigma−Aldrich Co.,Saint Louis,Missouri)をスラリーに加え、空気駆動の撹拌装備を用いて均質化した。生じたスラリーを、約0.4mmの側長、0.1mmの深さを有する切頭三角錐の複製パターンを含み、5重量%のエタノール溶液から乾燥して残留した鉱油の局所コーティングを有するポリエチレンシートに注入し、スキージを使用して、スラリーをシートの約400cm2の領域に広げて被覆した。次に、スラリーを含有するシートをヒートガンで乾燥させた。乾燥後、ウェブを激しく振って、その時には切頭三角錐の形状になっている生じた成形研磨材前駆体粒子を取り除いた。
