'''Ag<sub>2</sub>Na'''是一种二元[[金属间化合物]]，由[[银]]和[[钠]]组成。

== 制备及性质 ==
Ag<sub>2</sub>Na可以由[[银]]和[[钠]]的单质在750 °C反应，并在322 °C以下由包晶反应析出：<ref name=Feschotte>Feschotte, P.; Spitz, E. L. Domain of existence and stability of the Laves phase silver-sodium (Ag<sub>2</sub>Na). ''Journal of the Less-Common Metals'', 1988. 138 (1): 155-160. ISSN: 0022-5088. </ref>
:: <math>\mathsf{ 2 Ag + Na \ \xrightarrow{322^oC}\ Ag_2Na }</math>

它可以和水反应，生成纳米银、[[氢氧化钠]]并放出[[氢气]]：<ref>{{cite journal|last1=Wang|first1=Huabin|last2=Northwood|first2=Derek O.|title=Synthesis of Ag or Pt Nanoparticles by Hydrolysis of Either Ag<sub>2</sub>Na or PtNa|journal=Research Letters in Materials Science|volume=2008|year=2008|pages=1–4|issn=1687-6822|doi=10.1155/2008/619032}}</ref>
:: <math>\mathsf{2 Ag_2Na + 2 H_2O \ \xrightarrow\ 2 NaOH + 4 Ag + H_2 \uparrow}</math>
它也能和[[乙醇]]反应。<ref name=Feschotte />
