Understanding Refractory Failure—A New Perspective

This b/a value will give a starting point as to what type of refractory material should have been chosen. Here is one way to calculate the base-to-acid ratio: When the base-to-acid ratio is less than or equal to .25, it indies an acid condition. An acid condition would indie that a SiO2 type refractory should be considered. When the base-to-acid ratio is greater than .25 but less …
