This is probably the only metal oxide that is covalent.

Far from it, covalent and ionic are just two extremes, metal oxides cover the whole range in between. See for example manganese heptoxide, Mn₂O₇. Physchim62 10:33, 7 October 2005 (UTC)[reply]

Thermal conductivity[edit]

The thermal conductivity of BeO at 0°C is typically around 330 W·m⁻¹·K⁻¹, which is comparable to that of pure copper. Anyone know how to add this to the chembox table? DFH 20:53, 23 November 2006 (UTC)[reply]

But it is an electrical resistor, unusual. 12.10.127.58 21:11, 22 December 2006 (UTC) What is unusual? — Preceding unsigned comment added by 81.9.23.139 (talk) 14:40, 24 June 2011 (UTC)[reply]

Merge involving American Beryllia[edit]

The article American Beryllia Inc. has been created recently (Nov 2007) and is currently nominated for deletion via the PROD-path. The claim in this article is that it is one of two manufacturers of beryllium oxide remaining in the United States. I have nominated the article by way of mergeto/mergefrom templates for merger into this article as a company which produces beryllium oxide and which has no mention of other products in the current stub article. Input from someone familiar with the manufacturing status of this material in the United States and/or outside the United States would be appreciated. --User:Ceyockey (talk to me) 01:03, 26 November 2007 (UTC)[reply]

Problematic use of SystematicName for Beryllium oxide[edit]

The main discussion on this issue is held at WikiProject Chemicals. Please report your reactions and comments there. Shinkolobwe (talk) 17:44, 25 December 2010 (UTC)[reply]

See hereafter, an excerpt from the chembox of beryllium oxide:

| ImageName = Unit cell ball and stick model of beryllium oxide

| IUPACName = Beryllium oxide
| SystematicName = Beryllio-λ¹-oxidanyl (substitutive)

Oxidoberyllium (additive)

Question: Is it meaningful to present the substitutive name as systematic name for beryllium oxide in Wikipedia ? The composition name and the additive systematic names are both simple and very clear. However, the substitutive name does not seem to make sense to describe a solid compound made of a hexagonal network of beryllium cations and oxide anions. Such a complex name would be appropriate to describe the structure of a single molecule (i.e., an isolated moiety), should this one exist, but not for describing the unit cell repeated in a crystalline network. It seems that here the nomenclature logic is once again pushed behind its reasonable limits by User:Plasmic Physics. I have not verified myself with the IUPAC Redbook (IUPAC nomenclature of inorganic chemistry 2005) if the substitutive naming is correct or not.

The immediate consequence of systematically extending the use of such useless names (if not incorrect at all) to all inorganic compounds in Wikipedia is to puzzle even more the reader than to help him. Nearly nobody will use this intricate nomenclature and the risk to mislead the audience is not negligible.

It is worth to question us before accepting to altering/polluting thousands of chemboxes with such low-value information. Again here, common sense and self-critic mind are necessary: what is the the aim and the added value of such overspecialized edits. My opinion is that when writing often less is more. Thank you for your opinions and comments. Best regards, Shinkolobwe (talk) 17:33, 25 December 2010 (UTC)[reply]

One thing is sure: the artificial BeO should not be called bromellite. It is structurally identical, but it is not genetically identical (mineral names should be used for minerals = naturally formed substances).Eudialytos (talk) 22:30, 4 November 2017 (UTC)[reply]

Diradical[edit]

As a general rule main group element compounds are in the singlet state in the vapour phase. I cannot find a reference to back up the assertion that this is a diradical, if no one can reference it this statement should be removed because it is quite possibly wrong. — Preceding unsigned comment added by 2.125.53.160 (talk) 22:51, 7 November 2011 (UTC)[reply]

Corrected. Plasmic Physics (talk) 11:58, 8 November 2011 (UTC)[reply]

Photographs[edit]

A photograph is required suitable for the chembox as per the description. It is a good idea to add another picture to the article space showing the white amorphous solid or powder. Here is an example: crystalgrowing.com. Plasmic Physics (talk) 11:58, 8 November 2011 (UTC)[reply]

Bonding in BeO[edit]

Probably easier and more rigorous to describe bonding in diatomics using MO theory vs hybridrization approach. Organic chemists, who are generally untrained in Group Theory, rely on hybridization because it predicts shapes (but not spectroscopy). Most modern textbooks on inorganic and theoretical chemistry have abandoned that approach and rely on MO theory. Much blood has been spilled over the difference, but since Pauling's death (he was the advocate for hybridization), MO has taken hold.--Smokefoot (talk) 14:10, 8 November 2011 (UTC)[reply]

It's still taught at universities. I find that it helps to predict MO theory. Plasmic Physics (talk) 21:12, 8 November 2011 (UTC)[reply]

Whatever, good luck mastering it.--Smokefoot (talk) 14:40, 9 November 2011 (UTC)[reply]

Color of minerals[edit]

Let me get this straight: Editors are now going to comment on the appearance of mineral specimens when the colors do not agree with their notions of what pure compositions look like? That practice might be a bad idea, as well as a form of original research. --Smokefoot (talk) 14:40, 9 November 2011 (UTC)[reply]

There are two issues regarding the colour of minerals: the original colour (in this case: almost exclusively colourless and I haven't ever seen a coloured bromellite) and the colour of its powdered form (this is very often different, if we may call the lack-of-colour different from white).Eudialytos (talk) 22:30, 4 November 2017 (UTC)[reply]

Very high similarity to diamond[edit]

This isoelectronic with carbon and boron nitride compound is really similar to diamond.

Similarities are: 1. very high hardness 2. very high melting point and boiling point 3. very high density compared to atomic masses of elements 4. very wide band gap (10.6 eV BeO, 5.5 eV diamond) 5. really high thermal conductivity 6. colorlessness 7. similar average electronegativity (BeO - 1,57 + 3,44/ 2 = 2,505, diamond 2,55)

Is there any colective name for materials similar to diamond?

Transistors[edit]

Due to its high thermal conductivity it's used as a heat-transfer compound in powdered form. I used to open TO-5 (metal-can) transistors, only to find they were full of this white powder which I assume was BeO. 108.213.76.24 (talk) 21:11, 1 August 2015 (UTC)[reply]

Lithium Fluoride[edit]

According to the Lithium Fluoride article, BeO has the highest specific energy of formation (lithium fluoride is second). Should this be added into this article? Apricot2000 (talk) 18:08, 8 January 2021 (UTC)[reply]
