CalcZAF and Standard / Re: How to treat massive of data in CalcZAF?
« Last post by Probeman on Today at 05:49:43 PM »
I done it, thank you.
And what next?
System did something and propose to save something.
OK.
But where I can find initial data and calculated results?

Results will be in the "save something". It also asks whether to export the "save something" results to Excel.

I have a lead on potential sources for ZrO2 and YAG (Y3Al5O12). Does anyone have experience with materials from the Shelby Gem Factory? They were a world renowned synthesizer of several gemstones and apparently invented a technique for synthesis of CZ (ZrO2) using the Czochralski method. The factory closed in 2019 and all of the remaining stock was sold in bulk. I met a local gem dealer who claims to have obtained “hundreds” of pounds of bulk gemstones from the owner when it closed. I purchased ~7 g pieces of colorless ZrO2 and YAG. I will mount and test them for crystallinity and trace impurities to evaluate if materials from the Shelby factory could be suitable for our purposes.

But if I right, I can not recalculate in CalcZaf more then 1 point for one time. Only point by point. Is it true?

I repeat:

To have CalcZAF re-calculate *all* the points in the imported DAT file, simply use this menu to open the .DAT file:

Hi Probeman - thank you for show me the combine possibility.
But lets come back to my question.
I need to use CalcZaf for 2 option:
1. To recalculate data PFE software which were measured on a different Probe by different hands.
2. To recalculate data Jeol software which were measured on a different Probe by different hands.
In the both cases I have more then 1 point.
But if I right, I can not recalculate in CalcZaf more then 1 point for one time. Only point by point. Is it true?

JEOL / Re: Change in peak shape over time
« Last post by Changkun on November 30, 2021, 03:49:09 PM »
An update on this old thread:  As of this morning, JEOL has agreed to replace our three PET crystals (PETJ, PETL, and PETH) at no charge to us.  This is fantastic news and is very gracious of them.
We have the same issue on PETL and PETJ crystals in 8530F.
When the "electrostatic deflector" switch is toggled on/off, we can see the brightness change (but not so largely.)
Was there another reason to cause the peak shape change with PET crystals rather than static filter issue?
Could you let us know how and why JEOL factory decided to replace your PET crystals with new ones?

Thanks,
Changkun

Hi Probeman,
I followed all your recommendations but not understood, how I can work with more then 1 point in CalcZaf.
I want to use 2 options:
1. use the CalcZAF export menu from Probe for EPMA - I saw just 1 point in CalcZaf table, how I can see more then one?
2. manually input to CalcZaf my data (from JEOL soft? for instance) - everything is clear if I calculated one point, but how I can calculate more then one.

Hi Rom,
I had to re-read this topic to see what you exactly are trying to accomplish and it seems you are wanting to re-calculate all analysis points in Probe for EPMA using all 10 matrix corrections. If that is what you want to do, why don't you just use the Use All Matrix Corrections" checkbox as described here:



and then click the Analyze! button and you'll get the output for the 10 matrix corrections in the log window:



Remember you can also combine points from multiple samples in PFE (up to 500 points) using these buttons:



As for CalcZAF, if you really want to re-process your PFE data in CalcZAF (why?), you can certainly export all the data using a right click in the Analyze! window or from the Output menu, but after importing your data into CalcZAF, it only displays one point at a time. Then use the Load Next Dataset From Input File, to see the next point.

To have CalcZAF re-calculate all the points in the imported DAT file, simply use this menu to open the .DAT file:



But I think you're better off just using Probe for EPMA.

EPMA Standard Materials / Re: An Open Letter to the Microanalysis Community

Excellent advice.

Would you be able to help us locate some high purity ZrO2? And also perhaps some single crystal borides?  We only need a few grams to start our initial testing of purity and stoichiometry. Later we will want quotations for 500 to 1000 grams.

If you know of specific sources we would love to hear from you. This is a crowd sourced project, if we don't do it, no one else will.

Please send any written quotes to Will Nachlas:

Will Nachlas <nachlas@wisc.edu>

or add the quotation information to our Google spreadsheet:

https://docs.google.com/spreadsheets/d/19AeXvxIaP6qvChbE7cxK05B_6rkZSN14T-7ZJ7nkm8M/edit*gid=0

We need all the help we can get, thank-you!

FIRM WRITTEN price quotes are the first step.

Note added next day:  Also required would be the minimum order whether in kilos or $$$.

The "cost to synthesize" does not include the cost of raw materials.  Hf-free Zr will cost a lot more than natural Zr.  Then  there is the cost of making ZrO2 powder, then the recrystallizatio

ZrO2 is usually stabilized with Y2O3: better make sure your spec is precise.  You may not have an option if the transition from low symmetry to cubic is below the melting point.  Charles Taylor had natural ZrO2 with 0, 5%, 10%, 15% and 20% Y2O3.  Below 15% Y2O3 the pieces were crappy polycrystalline dust.   But who knows where all that got to?

One  reason to avoid LaB6, CeB6 etc is the extremely high melting point.  Materials are usually sintered--pressed in a furnace but not melted.   Commercial RSi2 is a mix of R rich and Si rich phases , each phase about 1 micron across.
