The melting point range of mixed raw minerals containing silicon and aluminum, is reduced. They are melted in a ladle, with air introduction. A nozzle-blowing operation forms the mineral fibers. The composition is expressed in mass percentages by: SiO 235-75, Al 2O 317-38, TiO 20.01-1.5,...
Furthermore, it also improves the properties of phosphate-free refractories. Moreover, BaSO4 is relatively stable and refractory--it is not known to decompose and has a melting point of 1580° C. BaSO4 is readily available in native form under the name barytes and is relatively inexpensive. ...

of leather, paper, wood or plastics, are bonded together by applying to at least one of the surfaces a melt adhesive comprising a polyester having a melting point of 160-220 C. prepared from (a) terephthalic acid or an ester thereof or a mixture thereof with isophthalic acid or an ester...
The composite anti-slagging melting inhibitor used for converting low-melting point carbon-containing substances adopts high-alumina fly ash as a raw material, and is prepared through pickling the high-alumina fly ash, and adding kaolin, wherein a molar ratio of silicon to aluminum is 1-2:2-...
Kaolin, by melting it, without the addition of a fluxing material, by burning a carbonaceous fuel in contact therewith, the product having a fusion point above 1370 DEG C. and a devitrification point above 815 DEG C. The product, which p may contain 0.05 - 1.0 per cent of carbon, is ...
This research primarily examines the co-combustion of Ordos bituminous coal (BC) and corn stover (CS) and investigates the ash fusion properties post-co-combustion through the use of additives. Techniques employed for analysis include an ash fusion point tester, X-ray fluorescence (XRF), and X...
For example, many active compounds are formulated as liquids because the low melting point of the active compounds makes it excessively difficult, or even impossible, to formulate a stable, effective solid formulation. The present invention provides solid formulations of low melting active compounds, ...
Preferably the organic compound is at least one isothiazolone biocide having a melting point of 35-45 deg.C; the inorganic filler comprises titanium dioxide and kaolin; and the solvent is at least one selected from a diglycol solvent and a triglycol solvent. Preferably the organic compound ...
The DT, which stands for the starting point of melting and is therefore frequently used as the reference temperature in laboratories and thermochemical facilities [62], was higher for the CaCO3 than Ca(OH)2 additive, but altogether, the DT did not record a more significant change. Thy et ...
