Refractories: Recent Developments in Materials,
Production and Use
Advisory Board
Invited Lectures


This symposium will focus on recent advances in refractories as high temperature insulation and containment materials for severe service environments in the following areas: advances in refractory raw materials and product formulations; mixing, installation, drying, firing and/or property development in monolithic refractory materials; refractory performance issues related to industrial demands; standardization of refractory testing and/or the need for specialized tests; environmental issues or energy conservation related to refractory processing or use; the use of quality control and analytical tools to improve refractory quality and consistency; modelling refractory wear or user systems and improving refractory performance through system modifications or engineered materials; and the use of post mortem failure analysis to resolve refractory issues or improve refractory service life. Improvement in refractories are driven by changes in energy and raw material cost/availability, advances/changes in refractory technology, changes in the users production environment leading to new material demands, the need for rapid and reliable technology to install refractories that minimize production downtime, and the constant need by refractory users for lower production/material costs with maximum performance. This symposium will cover novel research and development advances related to prefired shaped and unshaped monolithic refractories composed of oxide and nonoxide components and their combinations; including additives or refractory components such as binders, cements, carbon, flow modifiers, antioxidants, and set time modifiers. Contributed papers will cover achievements and challenges from the perspective of either the refractory user or producer.
