can you suggest any material or coating which is refractory in nature and having excellenent erosion resistence against liquid melt of 1400 deg. centigrade.the coating shall give a min. delta T of 300 deg.centigrade?

It looks like a ceramic of some sort will withstand this.

Or how about firebrick?

Follow PW's hint and look into flamespraying ceramics.

We really need to know what the melted material is, what the base container is, and what temperature cycling is present. The refractory must be chemically resistant to the melt and strong enough to withstand thermal cycling (and exposure to the vapor above the melt)
