Characterisation and properties of aluminium/zinc oxide composites as catalytic gases from depolymerisation of low density polyethylene to liquid oil

The effects of addition zinc oxide (ZnO) or magnesium trisilicate (MTS) in aluminum (Al) matrix composites on physical and mechanical properties at different sintering temperature were studied. The Al/ZnO and Al/MTS composites prepared by powder metallurgy (PM) method. The composites were mixed usi...
