Magnesite - Open Access .click

Refractories and Industrial Ceramics, 2022
The composition and properties of two types of calcined magnesium oxide powders, differing in chemical composition, are investigated. The difference in chemical and phase composition determines the different behavior of powders during firing, which is smoothed only at a temperature of more than 1850 °C.

Effect of Magnesite Diameter on Magnesite Reforming Rate

KAGAKU KOGAKU RONBUNSHU, 2005
マグネサイト改質速度におよぼすマグネサイト粒径の影響を実験的に検討した．マグネサイトのみを加熱した場合，粒径が大きくなると分解速度定数は小さくなった．マグネサイトに硝酸マグネシウム6水和物を混合した場合，粒径10−3 m以上では，マグネサイトのみかけの分解速度定数が無添加の場合とほぼ同じであった．一方，マグネサイトの粒径が10−3 m以下の場合，みかけの分解速度定数は粒径の−2乗に比例して大きくなることがわかった．

Magnesite Enrichment withPseudomonas oryzihabitansIsolated from Magnesite Ore

Geomicrobiology Journal, 2015
Magnesite is a primary source of magnesium and its compounds. The major problem in its practical use are the impurities such as silicon, iron and calcium carbonate. Some magnesite ores in Turkey cannot be used due to a high amount of CaCO3 (≥3%). In this study, bacterial isolates from magnesite quarries in Mersin were tested by plate assay for their ...

Magnesite-chromite products from high purity magnesite and chromite

Refractories, 1971
Products made from magnesite and chromite with low-impurity oxide concentrations possess better thermal factors than ordinary periclase-spinel refractories: refractoriness under load: 1700°C and above; bending strength at 1300°C 2.5–3 times greater; deformation 3–4 times; and the rate of deformation at steady-state creep is about a half.
