KINDIRECT PRESENTS A PARADIGM SHIFT IN METALLIC POWDER PRODUCTION
Most metals are inherently reactive and are thus rarely found in their pure form in nature.
Instead, they exist in inorganic ionic compounds, where the charged metal atoms (cations) are paired with counterparts of one or more non-metal elements such as oxygen (oxides), chlorine (chlorides) or other complex polyatomic ions. These compounds are mined and extracted from mineral ores that are processed and purified through physical and chemical means before producing ingots and end metal products. Conversion of the positive metallic atom (cation) within an inorganic compound to its pure form is known as “reduction”.
is a highly energy-intensive process that results in high capital, operating and (often less visible) environmental costs.
Many established and emerging advanced manufacturing processes have created a demand for metals in highly micronised and even nano-powder form. This adds a further layer of energy intensity (for crushing and grinding) and complexity in achieving the desired particle size distribution.
KindirectTM is a proprietary, single-step aluminothermic reduction process for metal oxides that more than halves the energy requirements, while giving control over final product composition based on starting materials and gentle processing conditions.
KindirectTM results in minimal waste and emissions compared to conventional technologies and takes advantage of recycling intermediate chemicals used in the production cycle. Due to the reduced complexity and manageable operating conditions, KindirectTM is highly modular and scalable to respond to shifting demand.
