A. You can call the Indium corporation in Singapore and ask about buying stock. It usually comes from zinc ores and about a quarter of the stuff comes from Canada, so shop among the mining companies, say on the Toronto exchange. Oh, yeah, Intel is going to be using a lot for its optical digital projects.

Asked by Canda - Tue Sep 2 09:28:27 2008 - - 2 Answers - 0 Comments

A. First thing is ..Good For You!!! It is always a good practice to check MSDSs for material you are working with. The principle hazard for indium solder is the lead content, although the antimony and other metals should also be treated with respect. Check out the following to find the MSDS for indium solder. You should probably get the MSDS specific for the mfr/brand you are using.

When indium reacts with oxygen, the most likely formula for the oxide produced is?
Q. Hey all, So I know that Indium is in group III so it will prefer a +3 oxidation state. O in group VI will have a -2 state. I just can't figure out the formula that will generate a neutral compound given those oxidation states. (I thought it would just be InO2, but I was wrong). Could anyone explain to me the method for determining the compound that would be produced? Thanks a lot!
Asked by DrkWarlock - Mon Apr 27 20:40:15 2009 - - 1 Answers - 0 Comments

A. You have to find the common denominator between the two oxidation states,one that gives a neutral salt. the first common denominator of 3 and 2, is 6. So if In is +3, how many do you need to have +6? (answer: 2) If O is -2, how many do you need to have -6 (answer: 3) Therefore, the neutral compound should be: In2O3 P.S. I'm just going by what the asker stated. I'm not checking to see if In really has a +3 oxidation state or not.

How do I find the mass spectrum for Indium?
Q. Indium (Z=49) has two stable isotopes In-113 and In-115. Using the weight reported on the periodic table, draw the mass spectrum for Indium. I tried: 113x+115y=114.8 to the the percentage for each isotope, but when I found x, I found y=0. What are the steps to drawing a mass spectrum?
Asked by Lexie - Sun May 25 15:49:49 2008 - - 2 Answers - 0 Comments

A. First off, the average atomic mass (114.8) is close to 115 so you should have a high percentage of that and a small percentage of 113. Let x be the decimal % of In-115. Then 1-x = the decimal % of In-113. thus 113 (1-x) + 115 (x) = 114.8 113 - 113x + 115x = 114.8 2x = 1.8 x = 0.9 = 90% In-115 and 10% In-113.

Asked by Ivy - Mon Aug 17 18:41:50 2009 - - 3 Answers - 0 Comments

A. The melting point for indium is 313.8773 F. So below that temp it is a solid. Assuming room temperature of 76.3 F the indium sample would be in a solid phase and yes it is a metal. Wikipedia has a complete collection of elemental characteristic and a great resource for problems like these( melting point, boiling point, laten heat, etc.)--sometimes much easier to access than hand books even. Just a good to know fact.

A. The chalcogenide semiconductors (e.g., CuGaSe2, AgInTe2, etc.) have lower melting points relative to their band gaps than the binary compound semiconductors (e.g., CdTe) or, even more so, the elementary semiconductors (e.g., Si.) This can be a great convenience. It's only recently that the technology has developed to make these compounds with precise stoichiometry and thus make possible precise doping. I published a paper way back in 1965 on two of these compounds in J. Phys. Chem. Solids. It was a piece of work before its time and was not appreciated.

Asked by Jazzy - Thu Dec 24 01:32:36 2009 - - 2 Answers - 0 Comments

A. You must pay attention to the data you submit when asking a question. I know that chlorates decompose with heat to produce the metal chloride and oxygen. But I cannot find that this is true of chlorites. Then there is the confusion as to whether you are dealing with aluminium or indium. The most common chlorate used in this method of preparing oxygen is potassium chlorate ( with MnO2 as a catalyst). Please check you question carefully and resubmit. It cannot be answered as it stands.
