I have two synthetic zircons in my standard collection. Both are clear single crystals and seemingly quite stoichiometric and pure. The first zircon crystal (#256) was grown by John Hanchar at Memorial University in New Foundland and the second (#257) was grown by Lynn Boatner at Oak Ridge National Laboratory some time ago.
What I would like to know if whether there is any data available for trace elements in these materials as I unfortunately do not have enough material for bulk ICP-MS or other trace characterization techniques. Perhaps the purity of the starting materials is known by someone?
Has anyone any trace element information on these materials?
