PARSED CONTENT

The site refractory.bigsite.ir states the following, "Alumina Al2O3 refractories are the part of alumina- silica group of refractories." I noticed that the webpage also stated " They differs from fireclay refractories in term of Al2O3 content and normally have Al2O3 content of more than 45 ." They also stated " The raw material base for these refractories are different than the fire clay bricks. According to the Al2O3 content, alumina refractories can be divided into. The main crystal phases of these refractories are mullite as major ph." The meta header had refractory as the first keyword. This keyword was followed by refractory which isn't as important as refractory.
