Preamble
Dear Readers,
Refractories play a key role in all high-temperature applications and cover all the strategic industries such as steel, cement, glass, petrochemicals, energy plants etc. Under the global worldwide faltering economy in the last 15 years the steelmaking industry has triggered refractory makers to improve durability, reliability and workability of refractory materials accompanied by cost reduction. Today the price explosion of raw materials as well as environmental related restrictions challenges the refractory companies as well as the scientific working groups for a continuous development of innovative approaches in material design, material processing and product functionality.
The understanding of their mechanical, thermal, chemical and functional properties as controlled by their structure at nano-, micro- and macro-levels followed by chemical and physical interactions at interfaces/surfaces is an unlimited tool for continuous development and innovation. The focused work of different scientific disciplines under the aspect of applicability is of a great importance to attract young scientists for innovation in this industrial sector. The performance as well as the competitiveness and especially the sustainability of the refractory companies are directly interlinked with the availability of well-educated young engineers by understanding refractories as multifunctional advanced ceramic components.
In 2009 the German Research Foundation (DFG) initiated a six-year Priority Programme SPP 1418 entitled “Refractory Initiation for Lowering Emissions” for applied fundamental research in refractories by bridging different material disciplines and understanding refractories as multi-functional ceramic components. The main goals are lower emissions in high-temperature applications thanks to the impact of refractory innovations such as development of new carbon bonded refractories with less carbon and development of oxide materials with improved thermal shock performance. Nanoengineered refractories, multilayer designs of refractory coarse grain sizes, incorporation of eutectical coarse grains in the refractory matrix etc. are some of the ideas that are supported by new testing approaches as well as simulation and modelling of the microstructure behaviour under thermal shock conditions.
The international community follows these activities, understanding the importance of the DFG’s Priority Programme by generating international congresses under the banner “Refractories Technology to Sustain the Global Environment” (Kyoto, Japan 2011), “Refractories Serving the Low-Carbon Economy” (Zhengzhou, China 2012) as well as “Refractories Solutions Through Innovations” (Calcutta, India, 2014) this year.
At this point I would like to thank all authors as well as review members, who promote innovation in refractories worldwide under an industrially oriented educational engineering umbrella. Enjoy the contributions and especially the visions to meet the new challenges in the high temperature sector based on ECO-Multifunctional Refractories.
