Boron-based Life - Tumblr Posts

I need some help coming up with an atmosphere compatible with boron-based life, I've already figured out the hydrosphere being composed of liquid ammonia and the planets temperature is -65c, and it orbits a K type star at 1.3 au and the star has a stellar mass of 0.65, if any of you know what the major atmospheric components would look like that would be a great help, i do have one request about the atmosphere not contaning highly errosive gasses
