1. A method of fabricating a burner element for an abatement apparatus, comprising:

multi-shot injection moulding comprising injection moulding a first charge having a metal powder and a flow compound and a second charge having metal particles, a flow compound and porogen into a mould defining said burner element to produce a moulded burner element wherein said injection moulding of one of said first charge and said second charge generates surface features shaped to enhance mechanical bonding between said first charge and said second charge; and

sintering said moulded burner element.
