A new and practical carbon paste electrode for insoluble

Dec 01, 2002· For the construction of the carbon paste electrodes, a brass wire with diameter 3.0 mm was immersed in the mixture graphite/paraffin heated at 70 °C, Fig. 1(1). Then, 5.0 mg of ground mineral was placed in a Teflon cavity with diameter 4.5 mm, Fig. 1(2) and the extremity of the wire covered with the hot mixture was immediately pressed on the pyrite particles placed in the mould.

Nanotechnology in castable refractory - ScienceDirect

Jan 01, 2019· In the case of CS containing castable compositions, shorter mixing times were required during water additions. This is mainly due to the high viscosity of CS containing mixes (about 10 mPa.s) compared to those with only water additions. CS doesn’t participate in any chemical change during water additions as observed in CAC or HA compositions.
