ويمكن تحويل الجرافيت إلى الماس بفعل

ويمكن تحويل الجرافيت إلى الماس بفعل ارتفاع درجة الحرارة (~ 20000 C) والضغط العالي (100،000 الغلاف الجوي) في وجود المعادن الانتقالية (مثل البلاتين). والماس الاصطناعي، ومع ذلك، هي صغيرة في الحجم واللون الرمادي بشكل عام لون، وبالتالي لا يمكن أن تستخدم الأحجار الكريمة. وتستخدم هذه لصنع قطع وأدوات الطحن.

It can convert the graphite to Diamond by high temperature (~ 20000 C) and high pressure (100, 000 atmosphere) in the presence of transition metals (such as Platinum). And artificial diamonds, however, are small in size and generally gray color, and therefore cannot be used as gems. These are used for the manufacture of cutting and grinding tools.
