This symposium will focus on the current “state of the art” in refractory liner materials and on the advances needed in material performance for existing and/or new processes, or by needs caused by modifications of existing ones.  Drivers for change; such as rapid changes in raw material availability, environmental concerns, technology changes, or the need for relevant information on refractory material properties or causes of failure; will be discussed.  Symposium topics will range from the refractory raw material formulation, manufacture, testing and installation; to analysis of refractory wear/failure causes; to controlling refractory wear and improving liner material performance using existing and/or advanced analytical tools or thermodynamic process modelling; to the increased energy, environmental, and education needs of refractory users and manufactures.  Contributed papers will cover achievements and challenges from the perspective of either the refractory user, installer, or producer; and will focus on shaped and unshaped (monolithic) refractory materials composed of natural and/or synthetic materials.      
Session Topics

CN-1 Raw materials needs

  • Natural raw material, their characterization and performance – including changing industry needs and material sustainability
  • New/improved refractory raw materials and additives (natural and synthetic) to meet shifts in refractory performance needs
  • Raw material phase relationships and reactions occurring during product installation, sintering, or use that impact microstructure development and/or product performance

CN-2 Product testing and quality control

  • Testing and improving physical properties; such as thermal shock, spalling, hot strength, fracture resistance, creep, thermal conductivity, and MOE
  • Quality control and analytical tool use to improve refractory product quality, consistency, performance, or that reduce unit cost
  • Evaluating and controlling monolithic materials property changes that occur during storage, mixing, installation, drying, and firing; including those caused by composition and additives
  • Continuously monitoring variables and/or material properties related to refractory failure in severe service applications
  • Microstructure analysis as it relates to material performance (using SEM, TEM, cathodoluminescence, high temperature confocal laser microscopy, optical microscopy, or other analytical tools)

CN-3 Product manufacturing and installation

  • Advances in refractory manufacture, installation, and/or system repair/maintenance
  • Monitoring refractory performance as it relates to material repair/replacement
  • Material or process additives impacting refractory installation or service life; including monolithic material installation and its rheological properties

CN-4 Modelling and simulation of the process environment

  • Thermodynamic modelling and its use to understand/control refractory properties/performance through predictions of material interactions and their control by managing process chemistry and/or temperature
  • Thermal and stress management through kinetic modelling (thermal profile, materials diffusion, crack propagation, sintering, grain boundary motion, phase transformation, etc.)

CN-5 Refractory failure analysis

  • Analysis of refractory liner corrosion/wear caused by slag, molten glass, metal, hot gases, particulates, or combinations of them to improve refractory performance
  • Determining the causes of refractory failure and the use of that information to make necessary system changes

CN-6 Refractory materials for novel or advanced applications

  • Fabrication and performance of ceramic liner materials made by additive manufacture
  • Electrically conductive/non-conductive liner materials for magnetohydrodynamic systems
  • Other novel application requiring high temperature severe service materials or protective barriers (including battery materials, high temperature microwave processes, or high speed re-entry vehicles)

CN-7 Future refractory education needs

  • Refractory education needs brought about by the changing workforce and business models, industrial environments, or changing process environments – what types of training/education is needed to meet those needs
  • What types of monitoring or standardized/specialized refractory tests are needed by industry that quickly and accurately ascertain industrial process performance
