In Part 2 of this series we dig deeper into the specifics of laterites, one of the two main nickel ore types and look at smelting, the most common processing technique.
Heather Allain, Executive Director, Materials Technology Institute (MTI), tells us about her passion for materials and the importance of MTI’s work to provide awareness of safe, reliable and sustainable materials use.
Let's dive into this new series of articles on sustainability, treatment processes and innovations in nickel production, starting with nickel ores.
The ambitious future of India’s rail infrastructure requires prudent investments that ensure its long-term viability. This is where nickel-containing steels play a vital role.
Solar farms are blooming in fields across the globe and producing a new crop: solar energy. Photovoltaic (PV) systems made up of solar panels, are fast becoming the most recognisable of renewable energy technologies.
Materials selection for any piece of equipment or a process system is rarely a simple task, unless you are exactly replicating something successful. Often engineers will have a checklist to help them narrow down the choices, eliminating groups of materials that are not suitable for various reasons. Austenitic 300 series stainless steels containing 7-35% nickel will have most if not all of the boxes checked for being suitable where a stainless steel is desired.
Each family of stainless steels has its strengths and weaknesses. Ferritic stainless steels have useful properties – a lower rate of thermal expansion, higher thermal conductivity, strong ferromagnetism and very high resistance to chloride stress corrosion cracking (SCC). When looking at selecting any alloys, it is important to consider all the factors for successful usage.
The duplex alloys are “problem-solving alloys” for good reason, they have been successfully used in many places where carbon steels and standard austenitic alloys have failed. Just like with the austenitic family, there are many different duplex alloys to choose from, with corrosion resistance varying from moderate with the lean duplex alloys to very high with the superduplex alloys.
The selection of an alloy should be guided by careful examination of the needs of the application. Before making a switch, it’s important to fully investigate an alloy’s strengths, weaknesses and applicability to your structure.
Think of the largest cruise ship. Then imagine how much it weighs – just over 100,000 tonnes, in fact. Now think about 500 of those ships, and what they weigh. That is the staggering amount of new electronic waste that we generate every year.
Even small quantities of nickel in an application can make a big difference to successful deployment.
Nickel-based alloys and nickel-containing stainless are playing key roles in an emerging source of renewable energy known as thermal solar plants or concentrated solar power (CSP). Their use has enabled the industry to overcome challenges in heat transfer and thermal storage technology.
“There’s a mental hurdle to get over of how inherently gross this could be, but we know that this water is safe, and we stand by our process.”
Geothermal energy for electric power production has a low profile yet is significant in the current and potential energy mix for a number of countries. It has also been described as the most reliable of the renewable energy sources, above weather-dependent wind, solar and hydropower.
The many new and innovative applications of hydrogen as fuel show great promise for a greener future.
As electric vehicles (EVs) trend from being niche to mass scale and the lines between EVs and their combustion engine (ICE) counterparts get blurred in terms of usability, consumers, automakers, governments and fire departments continue to have some apprehensions.
If you’re like me and predictive text has led to some awkward if not amusing moments, you might be sceptical about Artificial Intelligence (AI). But its achievements are already overwhelming and changing, even protecting, our lives in many sectors.
The present-day principal driver in the Li-ion industry is the large batteries required for electric vehicles. Due to the size of these batteries and the relative growth of electric vehicles it is predicted that the total Li-ion energy capacity will exceed one tera watt-hour by 2030. This anticipation for a dramatically rapidly expanding industry has stakeholders all along the value chain very motivated to be ready.
The last three months have been unprecedented. But amidst the chaos and despite the drop in global GDP, there has still been a considerable amount of activity in the electric vehicle (EV) and battery world.
Around two-thirds of today’s buildings will still be around in 2050, and by 2060, the world is projected to add 230 billion m² of buildings - an area equivalent to the entire current global building stock. What can the building and construction sector do to reduce the environmental burden of buildings?
