| titleOfInvention | A kind of siderochrome mineral black and preparation method thereof |
| abstract | The invention discloses a kind of siderochrome mineral black and preparation method thereof, include the following steps: to weigh Cr (NO with Cr:Fe 1~1.85:1 of molar ratio 3 ) 3 ·9H 2 O and Fe (NO 3 ) 3 ·9H 2 O is simultaneously added in the water that heating temperature is 50~70 DEG C, stirs and Cr/Fe aqueous solution is made；The incendiary agent reacted completely therewith is added, and continues heating stirring until all dissolutions；Mixed liquor heating evaporation is concentrated, then solution is placed in the Muffle furnace of 250~300 DEG C of heat preservations and causes self-propagating combustion；Combustion product is placed in high-temperature calcination stove, is risen to 850~1050 DEG C with 5~10 DEG C/min heating rate and is kept the temperature 1~3h, it is siderochrome mineral black that calcined powder is collected in cooling.The present invention is resulting between 0.1~1.0 μm of pigment particle distribution, the mellow and full rule of shape, and crystallinity is high.Product TSR >=31% is higher than similar products at home and abroad. |
