Luminous powder composition

Luminous powder can be used to prepare toys, craft accessories, silicone bracelets, artificial flowers, display night objects, clocks, telephone buttons, field instruments or indicators, transportation, etc. It has what ingredients make it so special and is favored in all walks of life.

    The luminous powder matrix is a component of an aluminate or a silicate. Some of the main components are CaF2, but they also contain a small amount of other impurity ions (complex composition), which leads to night light; if it is artificial, it is mainly SrAl2O4:Eu (green light), although other types are also available, but it is not popular. .

    The scientific name of rare earth long-lasting luminous powder after firing is: rare earth aluminate type long afterglow luminescent powder. Commonly known as rare earth long-acting luminous powder, long-acting luminous powder, long-acting luminous powder, luminous powder, the composition can be expressed as: Al2O3 (Sr, Mg, Ca) O: (Eu, La, Dy) B, its physical structure is oblique crystal Structure, weakly alkaline.

    The rare earth long-acting luminous powder is composed of SrCO3 strontium carbonate + AlO2 alumina + Eu2O3 yttrium oxide + Dy2O3 yttrium oxide + H3BO3 boric acid is formed into a block by high temperature 1400 ° C.

    Because the luminous powder has yellow, green, blue, white, white, white, white, green, orange, purple, red and other color luminous powder, the light of different colors, the composition is not the same.
