Conditions:
Compiler:
Methodology:
A visual polythermal method was used. The temperatures were measured with a Nichrome-Constantan thermocouple.
Sample Information:
- Analytical grade materials were recrystallized twice. The extrapolated fusion temperature of the lithium formate was 273°C.
Measurement Errors:
Ambient temperature: The compiler estimates the accuracy of the temperature measurements to be probably ±2 K.
Mass concentration (m/v) (1): No information is given.
System Components:
- Lithium formate, $\ce{ LiCHO2 }$; [556-63-8] NIST WebBook
- Lithium nitrate, $\ce{ LiNO3 }$; [7790-69-4] NIST WebBook
Experimental Data
Note 1: There is a eutectic at 162°C and 100 x1 = 55.
Note 2: The system was investigated at 0 ≤ 100 x1 ≤ 80.
