Four factors affecting the sintering of refractory

202071 The sintering of refractory materials is a complex process that is restricted by many factors The main factors that affect the sintering of refractory materials include the nature of the raw materials additives sintering temperature and holding time firing atmosphere and molding method and pressure of the green body 1

Dry sintering of refractory oxides at elevated

Recent efforts to explore the possibility of extending the service of aluminabased refractories into basic steelmaking operations have involved the appliion of a basic oxide veneer to both fireclay and highalumina substrates Because these investigations used a mineralogically complex system consisting of mixtures of commercial refractories and coatings the nature of the

Sintering Digitalfire

Sintering is just beginning What is sintering? Bentonite fired to 1950F in a small crucible It is sintering the particles are bonding even though there is no glass development The powdered mass is behaving as a unit the cohesive forces holding it together are enough to shrink the entire mass away from the walls of the container

REFRACTORY MOLDS FOR GLASS SINTERING

20161221 REFRACTORY MOLDS FOR GLASS SINTERING Recovered container glass can be formed into marketable products by filling a refractory mold with powdered glass and heating the glass and mold to a high temperature so that the glass sinters or bonds to take the shape of the mold The process creates high valueadded uses for recovered container glass

Sintering characteristics of activated alumina powder and

2020416 All along alumina powder has been widely used in the field of high temperature due to its high strength strong corrosionresistance and high hardness However because alumina belongs to the ionic bond crystal form the crystal form is large and the structure is stable so a certain amount of thermal energy must be provided to achieve sintering

Effect of different bonding agents on sintering behaviour

Refractory Mortar is a mixture of fine particles which are used in the form of a paste to bind refractory bricks after the addition of water to the mixtureThe composition and chemistry of the mortar need to be similar to that of the brick to be joined by the mortarThe service life of a refractory lining not only depends on the properties bricks but also on joints made by

Sintering Behavior Microstructure and Mechanical

Nearly fully dense carbides of zirconium hafnium and tantalum were obtained by pressureless sintering at 1950°C with the addition of 5–20 vol of MoSi 2 Increasing the amount of sintering aid the final density increased too thanks to the formation of small amounts of liquid phase constituted by MMoSiOC where M is either Zr Hf or Ta
