Magnesite converter brick made of Czechoslovak magnesite powder

Refractories, 1960
The magnesite and magnesite-chrome (periclase-spinel) parts made at the experimental plant of the Ukrainian Institute of Refractories with Czechoslovak magnesite powder are marked by high indices for density, refractoriness-under-load and heat resistance, and are only slightly different from the studied samples of Austrian converter brick.

Investigation of Calcined Magnesite Sintering

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.

On the Formation of Magnesite

1983
Deposits of sparry magnesite are widespread in both the low grade metamorphic dolomitic rocks of the Nordliche Grauwackenzone and very subordinately in the Innsbrucker Quarzphyllit of the Eastern Alps. In the investigated area there is strong evidence for a perturbated geothermal gradient due to a synmetamorphic overthrusting. Under such conditions Mg2+

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 ...

Large magnesite and chrome ? Magnesite refractories for open-hearth furnaces

Refractories, 1970
In the production of large articles M-5, KhM-13, and KhM-14 instead of standard products M-1, KhM-1, and KhM-3, the output of the press increases by 4–5 tons per day, and there are also increases in labor productivity for manual operations.

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.

Utilization of caustic magnesite dust in the production of sintered magnesite powders

Refractories, 1984
A method of obtaining magnesite powder and the appropriate charging equipment have been developed which make it possible to utilize effectively the caustic dust removed from the effluent gas of rotary furnaces. A feature of the new method of obtaining the powder includes the periodic alternation of the firing of dust and a mixture of it and raw ...
