Er...is a single wafer (electronics) $100k, or did you mean a boule (crystal)? Do you have a source for that one?--Joel 01:54, 16 July 2005 (UTC)

Heh, you caught me. I was referring to each wafer, which can produce dozens of chips each; but the cost number is 3rd-hand hearsay. I'll look for a source. :) - Bantman 02:37, July 16, 2005 (UTC)

No worries. I actually think the price of the boule is more important for this article, since a lot of the cost of a wafer is cutting and polishing it so precisely and in such a clean environment. The information you gave would go well on the wafer article, however. This is a good start for an article all around; kudos. Some day I'll mention gemstones and turbine blades, if you don't beat me to it.--Joel 16:12, 16 July 2005 (UTC)

Thanks for the kudos! It's always nice to have one's work recognized. I've scratched the cost estimate; I think you're right that it's most likely in the cutting and polishing, and not growing the boule. A cursory internet search seems to confirm that prices for raw single-crystal silicon isn't all that much. - Bantman 19:40, July 16, 2005 (UTC)

Delisted GA

There are no references or images. slambo 16:53, 23 October 2005 (UTC)

crystalline copper

Why is the link treated like an external one? --Shanedidona 16:01, 28 November 2006 (UTC) The topic of crystalline metals is not explained at all or well incorporated, also missing many other types of metals Bookrabbitwitch (talk) 21:26, 4 February 2021 (UTC)

Tone and Tidiness

Article reformatted - uses now not a bulleted list - removed references to "monocrystalline copper" - It requires a better reference than some marketting material to prove this. (also Crystalline copper has issues too)

Should the manufacturing be covered in the individual uses sections - as the different making methods differ a lot?FengRail (talk) 20:04, 4 April 2009 (UTC)

“But there were surprises in store” Very casual writing in the electrical conductors second to last paragraph. Bookrabbitwitch (talk) 21:27, 4 February 2021 (UTC)

merge crystalline copper

Suggest merging what parts of crystalline copper can be shown to be true into this article.FengRail (talk) 20:20, 4 April 2009 (UTC)

Sub-heading and Heading Reorganization

Proposing to move Materials Engineering under "Uses" to "Manufacture" heading for cohesiveness. Bookrabbitwitch (talk) 07:05, 30 January 2021 (UTC)

Citations

Use of Fluorite monocrystals as apochromatic refracting telescopes needs a citation. Bookrabbitwitch (talk) 21:30, 4 February 2021 (UTC)

The first source which is for a mention of turbine tech is from Rolls Royce. Bookrabbitwitch (talk) 21:30, 4 February 2021 (UTC)

Three out of six seem to be Korean heavy groups but otherwise a good mix of primary and secondary sources. There aren't enough sources at the moment to describe a diverse array of authors and publications. Bookrabbitwitch (talk) 21:30, 4 February 2021 (UTC)

Unsure about the singular link under the further reading, which is a powerpoint for a summer school and summarizes crystal growth. Bookrabbitwitch (talk) 21:30, 4 February 2021 (UTC)

Turbines

Thinking of making the single crystalline turbines a separate section since it is a significant application. Bookrabbitwitch (talk) 21:33, 4 February 2021 (UTC)

Single Molecule Magnets

Thinking of including SMM's as a use towards the end as a new field being studied. Will include specifications on molecule vs single crystal. Bookrabbitwitch (talk) 21:34, 4 February 2021 (UTC)

Electrical Conductors

This section has specific information on the metals in the third and fourth paragraphs that I did not put in. I could not find the referenced materials to cite, but did not want to delete. If someone could either refute or agree about deleting some of the information, this section should discuss it. Bookrabbitwitch (talk) 03:38, 12 March 2021 (UTC)
