A method of fabricating a burner element for an abatement apparatus is disclosed. The method comprises: injection moulding a charge comprising metal particles and a flow compound into a mould defining the burner element to produce a moulded burner element; and sintering the moulded burner element. In this way, injection moulding is used to produce the burner element, which provides far more flexibility regarding the design and properties of the burner element and avoids the necessity of incorporating a perforated support into the burner element. This allows burner elements of more intricate design to be produced, as well as burner elements which are thinner than those produced using existing techniques, which increases the volume of a combustion chamber defined by that burner element for any external burner element size, which in turn increases the amount of effluent gas that can be treated for any burner size.
