Abstract

This article presents experimental data on the coefficients of viscosity and thermal and electrical conductivities, as well as the absorption spectra, of suspensions of ultradispersed diamonds. Suspensions of UDA-S and UDP-A detonation nanodiamond particles, as well as UDP-AG diamond–graphite powder, are used in the experiments. The concentration of nanodiamonds in distilled water is varied within a range of 0.5–5 wt %. It is shown that the technology of purification diamond powders from side products of their synthesis substantially affects the physicochemical properties of aqueous suspensions of these powders.

纳米金刚石水悬浮液输运系数的实验研究

摘要

本文介绍了超分散金刚石悬浮液的粘度，导热系数和电导率以及吸收光谱的实验数据。实验中使用了UDA-S和UDP-A爆炸纳米金刚石颗粒的悬浮液，以及UDP-AG金刚石-石墨粉。蒸馏水中纳米金刚石的浓度在0.5-5 wt％的范围内变化。已经表明，从其合成的副产物中纯化金刚石粉末的技​​术大大影响了这些粉末的水悬浮液的物理化学性质。
