This material's crystal structure happens to be the prototype for all commercial compound semiconductors. I might eventually want to calve off the zincblende and zinc blende redirect pages into an article on general properties of this crystal structure, with a navigational aid at the top linking to this mineralogy page. Otherwise, lots of materials scientists might come traipsing through here looking for info on GaAs, AlGaAs, InGaP, ...--Joel 00:00, 17 May 2005 (UTC)
The lustre of sphalerite is submetallic, rather than resinous as was previously stated in the article. It is listed in the submetalic lustre category. --turkeybrain 02:54, 21 August 2008 (UTC)
Most refs (Webmineral, Mindat) state adamantine to resinous (esp. for low iron), but high Fe varieties verge on submetallic (Dana's Manual). Vsmith (talk) 03:31, 21 August 2008 (UTC)
Shouldn't we add some basic chemical data such as melting point, solubility in water etc.? —Preceding unsigned comment added by 194.53.253.51 (talk) 14:51, 18 November 2009 (UTC)
Second that, especially since I'm told that sphalerite has no melting point, subliming at 1185 C. This seems like a pretty interesting property to me. 98.221.97.100 (talk) 19:15, 27 December 2010 (UTC)

See zinc sulfide. Sphalerite is mostly ZnS, but impurities/other phases (whose presence is common for most minerals) would change its properties, such as melting. Perhaps this is a reason why they are not listed in the mineral articles. Materialscientist (talk) 00:01, 28 December 2010 (UTC)
