YInMn Blue is chemically stable, does not fade, and is non-toxic. It is more durable than alternative blue pigments such as ultramarine or Prussian blue, retaining its vibrant color in oil and water, and is safer than cobalt blue, which is a suspected carcinogen and may cause cobalt poisoning. [26]
Indium metal does not react with water, but it is oxidized by stronger oxidizing agents such as halogens to give indium(III) compounds. It does not form a boride , silicide , or carbide , and the hydride InH 3 has at best a transitory existence in ethereal solutions at low temperatures, being unstable enough to spontaneously polymerize without ...
A flame test involves introducing a sample of the element or compound to a hot, non-luminous flame and observing the color of the flame that results. [4] The compound can be made into a paste with concentrated hydrochloric acid, as metal halides, being volatile, give better results. [5] Different flames can be tried to verify the accuracy of ...
YInMn Blue is an inorganic pigment with an intense blue color that was discovered by Mas Subramanian and his graduate student, Andrew Smith, at Oregon State University in 2009. [20] [21] It has been used in water, oil, and acrylic paints from paint vendors. The name "YInMn" comes from the chemical symbols for yttrium, indium and manganese. The ...
A pyrotechnic colorant is a chemical compound which causes a flame to burn with a particular color. These are used to create the colors in pyrotechnic compositions like fireworks and colored fires. The color-producing species are usually created from other chemicals during the reaction.
Predicting the color of a compound can be extremely complicated. Some examples include: Cobalt chloride is pink or blue depending on the state of hydration (blue dry, pink with water) so it is used as a moisture indicator in silica gel. Zinc oxide is white, but at higher temperatures becomes yellow, returning to white as it cools.
Indium(III) iodide is a pale yellow, very hygroscopic monoclinic solid (space group P2 1 /c (space group no. 14), a = 9.837 Å, b = 6.102 Å, c = 12.195 Å, β = 107.69°), [3] which melts at 210 °C to form a dark brown liquid and is highly soluble in water.
Organoindium intermediates do not react with –OH or –CO 2 H groups. Reactions with carbonyls, however, give high yields. Research has shown that in reactions of an indium intermediate with an electrophilic compound of both aldehyde and ketone, the reaction proceeded with the aldehyde. The electrophilic compound is shown below. [11]
