I'm performing an experiment based on slag corrosion behavior of the refractory material. I need to store molten metal at $\approx$ 1600-1700 K for that.

Specifically, I'm working on slag corrosion and penetration behaviour of refractory (MgO-MgAl2O4). I'm going to use immersion method, so in this method "Cylindrical or square pillar shaped samples are held in the corrosive liquid(slag) in a furnace. Immersion time, temperature and atmosphere can be varied" So, for storing slag+molten metal, I need to use a crucible.

Please suggest what would be the best choice of material for crucible. What is a crucible material?

I would suggest a silicon carbide crucible. The melting point is like 3000k which should serve your purposes. Also as I recall, it is inert to most molten metals.

You say you are testing slag with molten metal. What is the metal? Do you know what the slag is composed of?
