that occur during various reactions during the use of basic character
refractory materials used in the sinter region of cement rotary kilns cause
harmful toxic effects. Since magnesite-chromium refractories have this toxic
effect, alternative magnesite-spinel and magnesite-hersinite refractories have
been developed. Three different types of refractory materials
(magnesite-chrome, magnesite-spinel and magnesite-hersinite) were produced in
this work. These produced three different refractories are compared with a
variety of physical (density, porosity and strength and refractivity test under
load (RUL) and chemical (XRF, XRD) analyzes and microscopic structures. As a
result of the tests made, it was measured that there was no significant change
in density and porosity values ​​and that the strength value gave the best
result with 75.23 (N / mm <sup>2 </sup>) value in magnesite-hersinite refractor.
It is also determined from the RUL test that all three refractory materials can
be used between 1450-1500 ° C. </span> </p> <p> </p>}, number={5}, publisher={Sakarya University}
