“…Hardness measurements were performed on the submicron length scale using the NanoScan (NS) measurement system based on the principles of the scanning force microscopy [26][27][28]. Earlier this measurement method for hardness was tested on other hard and superhard materials, including the hardness measurements of c-BN, diamond and ultrahard fullerite [27,28].…”

“…They show low luminescence up to pressures of 270 GPa. 8 Synthetic IIa diamonds have excellent mechanical properties, 9,10 and have been used to generate very high pressures of 370 GPa. 7,8 Synthetic diamonds are still rare commercially, but are available from Sumitomo Electric and the Technological Institute for Superhard and Novel Carbon Materials (Troitsk, Moscow region, Russia).…”

Experimental aspects of Raman measurements at megabar pressures are considered. Features of diamond anvil cells working above 200 GPa are described. Problems of luminescence background at megabar pressures and the use of low-luminescence diamonds are considered. Methods of pressure measurements at very high pressures are discussed. The pressure dependence of the Raman shift from the diamond anvil tip was used as a reliable estimate of the pressure.

“…The hardness of diamond crystals containing 0.3 ppm of N is 175 GPa, and for crystals containing 200 ppm of N it is 151 GPa. 22 This shows that nitrogen incorporation makes diamond softer.…”

Important hard phases are included in the quaternary compositional system Si-N-C-B. This paper reviews ternary amorphous and crystalline phases in the system Si-N-C and deliberates on the issue of stability of the binary C 3 N 4 , a hypothetical phase harder than diamond, and instability of nitrides in general. There is a tendency for nitrogen atoms to agglomerate and be released as nitrogen molecules. Stabilization of CN radicals can be achieved through ternary phases: carbonitrides metal-C-N. Ternary Si-N-C phases have been synthesized by pyrolysis of polyorganosilazanes, physical vapor deposition, and chemical vapor deposition. The crystalline ␣-Si 3 N 4 :C phase can incorporate about 6 at.% C and yields enhancement of hardness and wear resistance. Other crystalline phases contain more carbon, for example, Si 2 CN 4 .
