ここで、前記Aは、二次元的に投影された粒子の投影面積であり、前記Pは、二次元的に投影された粒子の周長である。
[式1]
球形度=2(pi*A)1/2/P
ここで、Aは、二次元的に投影されたシリコン粒子の投影面積であり、Pは、二次元的に投影されたシリコン粒子の周長である。前記シリコン粒子の前記球形度は、走査電子顕微鏡から得られたイメージから、ImageJ(R)のような常用のソフトウェア、例えば、Imagej136を使用して測定される。または、SYSMEX社製(神戸所在)のFPIA−3000(R)というイメージ分析器(flow particle image analyzer)により、前記球形度を測定することも可能である。
平均直径が約5μmであるポリシリコン粗粒子を剪断圧力の大きさと時間が制御されたボールミル粉砕工程により、球形度がそれぞれ約0.4、0.5、0.6、0.7、0.8、0.9を含むシリコン粒子を製造し、球形度が0.95以上のシリコン粒子は、シリコン前駆体を利用して液状熱分解法により製造した。図6は、球形度が約0.8であるシリコン粒子の走査電子顕微鏡イメージである。分析されたシリコン粒子のシリコンの純度は、99%以上である。前記製造方法は例示的であり、他の研磨工程、またはシリコンロッドまたはウェーハのようなバルクシリコン材料を電気爆発して、前記シリコン粒子を準備してもよい。シリコン粒子の平均粒径は、約220nmである。
