Is it possible to react Rb + Al2O3?

hey friend your answer is
I am wondering if the Rubidium (
Rb
Rb
) in gas form can react naturally with Sapphire crystal (
Al
2
O
3
AlX2OX3
)? The temperature is
500 K
500 K
and the pressure is around
1 Pa
1 Pa
to
10 Pa
10 Pa
.
One of the reaction that comes into my mind is
4Rb+Al
2
O
3
⟶2Rb
2
O+Al
2
O
4Rb+AlX2OX3⟶2RbX2O+AlX2O
I was trying to calculate the Gibbs free energy of the reaction, but I could just find the Gibbs free energy for Rubidium and the Sapphire, which is
Δ
G
Rb
=53.1 kJ/mol
ΔGRb=53.1 kJ/mol
and
Δ
G
Al
2
O
3
=−1582.3 kJ/mol
ΔGAlX2OX3=−1582.3 kJ/mol
. I can hardly find the Gibbs free energy for the products.
Is there any other reaction that can occur naturally?
