  "id": "MLC-T-CHM-006385",
  "term": "KRS-5",
  "field": "Chemistry",
  "definition": "A mixed crystal composed of thallium bromide and thallium iodide (TlBr-TlI), used as an optical material for infrared applications. It is valued for its broad transmission range and high refractive index, although it is soft, toxic, and slightly soluble in water. KRS-5 is transparent to infrared radiation from approximately 0.6 to 40 micrometers, making it a suitable material for windows and attenuated total reflectance (ATR) crystals in IR spectroscopy.",
