A Process for Sintering of Diopside Prepared from Dolomite

Starting materials were pure SiO2 and dolomite raw materials. In order to improve the properties of sintered samples, such as the density egg white (ovalbemin) has been added into diopside. Furthermore, the effect of P2O5 addition on the sintering of the prepared diopside in the range of 0.5 to 5.0 wt% was studied as a function of the sintering temperature.

A Process for Sintering of Diopside Prepared from Dolomite

Diopside CaMgSi2O6 is an attractive material because of its applications. It was prepared by sintering the mixture at different temperatures (900°C-1300°C). Starting materials were pure SiO2 and dolomite raw materials. In order to improve the properties of sintered samples, such as the density egg white (ovalbemin) has been added into diopside.

Process for producing synthetic magnesite - dolomite sinter

Feb 20, 1979 · The prior art describes various processes for the production of magnesite-dolomite sinter from dolomite. One such process adds a magnesium hydroxide (Mg(OH) 2), commonly called brucite, slurry to hydrated dolomite to increase the magnesia (MgO) content. In another process, calcium compounds are chemically dissolved from the dolomite to produce a synthetic sinter containing up to .

The main chemistry of the sinter should meet the BF requirements and it should improve the quality of burden. The best advantage of sinter is that it is self fluxed. CaO (from Limestone) and MgO (from Dolomite) in sinter, eliminate the direct feeding of the flux in BF which minimises the cost of the hot metal. Sinter may be charged up to 80 % safely.

Jun 28, 2017 · Addition of dolomite through sinter is more preferred route since CO2 of dolomite is driven out during the sintering process. In case of sintering, dolomite is crushed to -3 mm (in the range of 85 % to 90 %) in hammer crushers before mixing it in the sinter mix. In case of direct feed to blast furnace, lump dolomite (10 mm to 30 mm size) is used.
