Since carbon nitride β-C_3-N_4 was predicted to be as hard as diamond, many efforts have been made to prepare the carbon nitride. Particularly, physical methods have been used for the preparation, such as pulsed laser ablation. However, there are not so many attempts to prepare β-C_3-N_4 by chemical method. We have prepared materials containing carbon and nitrogen as main components on the basis of the reaction mechanism which we have investigated in this research.Creamy white powders were obtained by the chemical vapor deposition of carbon tetrachloride and ammonia at 1000℃, followed by washing with boiled water. The composition of the material was C_3N_<5.1>O_<0.4>H_<4.0>, which was determined by usual combustion method and was similar to that of hypothetical hard material C_3N_4. The powders were harder than quartz whose Mohs hardness is 7. The hardness could be explained by the C-N single bond observed in the ESCA C_<1s> spectrum.

由于预测氮化碳β-C_3-N_4的硬度与金刚石相当，人们为制备氮化碳作出了许多努力。特别是，物理方法已被用于制备，如脉冲激光烧蚀。然而，用化学方法制备β-C_3-N_4的尝试并不多。在研究反应机理的基础上，制备了以碳和氮为主要成分的材料。将四氯化碳与氨水在1000℃下化学气相沉积，得到乳白色粉末，再用沸水洗涤。该材料的组成为C_3N_<5.1>O_<0.4>H_<4.0>，由通常的燃烧法测定，与假想的硬材料C_3N_4相似。粉末比石英硬，石英的莫氏硬度为7。在ESCA C_<1s>光谱中观察到的C-N单键可以解释其硬度。
