Ⅰ. INTRODUCTION As the superhard solids are materials widely used not only in industries (for example, in wire drawing, rock cutting operations and in heat sink), but also in scientific researches (for example, in high pressure generation and high pressure optics), their sintering and growing are very important problems. It is well known that diamond is a typical covalent bond superhard solid. Its sintering and growing mechanisms are very complicated and difficult to study because of the complexity of
