HIGH TEMPERATURE ELASTIC PROPERTIES OF REFRACTORY MATERIALS
Abstract: A pulse-echo technique, based on ultrasonic "long-bar" mode (LBM) velocity measurements, working up to 1700°C is described. Magnetostrictive transducers and ultrasonic lines used in a 40-85 kHz frequency range are detailed. The conditions of choice of fundamental parameters (frequency, line geometry, sample size) are discussed in relation with the nature and the microstructure of ...
متن کاملNEW REFRACTORY MATERIALS FOR THE COPPER INDUSTRY
Wear of various basic refractory materials to substitute to currently used magnesia chrome bricks has been studied, measuring matte and slag penetration and dissolution, through different cup and rotary slag tests. High magnesia with and without impregnation, magnesia graphite, magnesia-alumina spinel with and without impregnation, olivine-magnesia and olivine magnesia- graphite bricks, as well...
متن کاملCombustion joining of refractory materials
This paper overviews heterogeneous exothermic reactive systems as they apply to the joining of materials. Techniques that are investigated fall under two general schemes: so-called Volume Combustion Synthesis (VCS) and Self-Propagating High-Temperature Synthesis (SHS). Within the VCS scheme, applications that are considered include Reactive Joining (RJ), Reactive Resistance Welding (RRW), and S...
متن کاملradiopacity of dental materials: an overview
context this study aimed to provide an overview of the literature on the radiopacity of dental materials in order to emphasize its importance. evidence acquisition english-language literature was investigated using manual and electronic searches for the terms “radiopacity,” “dental material,” “cement,” “composite,” “ceramic,” “endodontic root canal sealer,” “bone graft,” and “acrylic resin” in ...
متن کاملDealing with Spent Refractory Materials
The disposal of spent refiactory materials has become a major problem for metals producers. The main issue surrounding refractory disposal is the elimination of the hazardous components of refractories, most commonly chrome-bearing materials and fluoride and cyanide in spent pot-liners. The various approaches to pollution prevention involve re-design to eliminate or significant reduction in was...
