refractory materials formula in austria

  • Formula for refractory cement | Details | Hackaday.io

    This is a formula for making excellent refractory material to use to line the walls of a melting furnace. I am routinely melting aluminum and brass and I have been looking for a formula that is strong and lasts a long time. All of the formulas that I have seen that use Portland cement need replacing pretty often because Portland does not hold up under heat.
