color classification about Sillimanite bricks


Posted April 12, 2016 by wanhaorefractory

Golden is due to ferric iron or in individual situations are as a result of trivalent chromium. Golden sillimanite combines with iron and 0.3 1.8% ......

 
Refractoriness of mobility than 1830 degrees increments the mobility combines with the Al content.

Sillimanite bricks has more items color, important has three species color variants: Golden, Maroon and basket color, which Golden and Maroon variants distribution more wide, and basket color variants is is mineral learn of curios, according to discussion, Cast Big Sillimanite Block in the of iron, chrome and titanium is decided its color diversity of important reason, while and its generated of schist environment phase relationship.
1, variant of schist, golden yellow is the thickness and symbiotic pegmatite has not altered the characteristics of sillimanite crystals. Golden is due to ferric iron or in individual situations are as a result of trivalent chromium. Golden sillimanite combines with iron and 0.3 1.8% combination of chromium.
2, Maroon sillimanite variant is also in the thickness variation in symbiotic pegmatite schist schist and composition. Maroon sillimanite combination Fe content greater than 1%.
3, blue silicone line stone and iron levels are low, the combination of iron is less than 1%, the combination of titanium to trace, spar with basket, color is very, very likely is the result of valence electrons between softened.
4, with a strong acid treatment concentrate, due to removal of sillimanite surface impurities, such as iron mask and red and Brown specularite, Brown golden color white or gray.
