Low melting temperature

MYRRHA is a multi-purpose research reactor able to operate in sub-critical and critical modes and currently in the design phase at SCK•CEN. The choice of LBE was driven by its chemical stability, low melting temperature, high boiling point, low chemical reactivity with water and air and a good neutronic performance.

In this work, we report the effects of decomposition of MnBi low temperature phase (LTP) into Bi and Mn during low-energy ball milling (LEBM) carried out in xylene and silicon oil protection solvent environments and its influence on the magnetic properties of MnBi as-milled powders. In both solvents, by LEBM for 120 - 150 min, MnBi arc-melted and annealed alloys were ground into fine particles of 0.5 – 5 µm to increase iHc up to 5 kOe.

Grafting acrylic acid (AA) onto linear, low density polyethylene (LLDPE) is carried out in melt state in the presence of styren (St). The effects of reaction time and temperature; concentrations of initiator and St; mixing speed of LLDPE and chemicals on the grafting degree of AA onto LLDPE is estimated. St is added to try to decrease the extent of crosslinking reaction and to increase the grafting degree of AA on to LLDPE. The obtained results show that the suitable conditions for the mentioned process above are 2 wt% of AA; 0.3 wt% of DCP; molar ratio of St/AA of 2.
