Nano-Borkarbid (B4C) Powder Description
Nano-Borkarbid (B4C) (CAS: 12069-32-8) is a black, metallic, glossy crystal. Its measured hardness is approximately 9.3 on the Mohs scale. This value is exceeded only by diamond and is numerically higher than that of silicon carbide. The chemical characteristics are stable. The material does not react with acid solutions. Its relative density is 2.52. The melting point is 2 350°C and the boiling point is above 3 500°C. Molten Borkarbid is capable of dissolving a significant quantity of graphite. In dilute acid solutions Borkarbid remains stable; however, it can be decomposed by a mixture of sulphuric acid and hydrofluoric acid or by a mixture of sulphuric acid and nitric acid.
Borkarbid exhibits a high thermal neutron absorption capability, high wear resistance and notable semiconductor conductivity. In many applications Borkarbid (B4C) is used as a control material in high temperature reactor designs. An increased concentration of the B10 isotope in Borkarbid improves the efficiency of neutron absorption.
