Remarks  

Attention: Thallium salts are toxic. KRS-6 is soluble in methanol, complexing agents and strong basics. Max. temperature for application: 200°C, easy deformable (cold liquidity).  Used less often than KRS-5

Remarkable 

• Rarely used thallium mixed crystal (TlBr0,4Cl0,6) with a lower transmission range than KRS-5
