About #2000^oC#.

Explanation:

The depth 1800 km is about the middle of the mantle that extends

from Moho discontinuity between Crust and mantle at about 60 km

to the outer core, at about 3000 km, where the temperature is

4000+^oC. The temperature, density and pressure increase with

depth. The temperature is likely to be around #2000^oC# at the

depth of 1800 km. The mantle layer here is supposed to be

seismically homogeneous.
