摘要： A METHOD FOR SEALING POROUS REFRACTORY JOINTS WHICH COMPRISES APPLYING A SILICATE GLASS TO A REFRACTORY JOINT, AND MELTING THE SILICATE GLASS IN ORDER TO FILL THE CONNECTING CHANNELS BETWEEN THE PORES AND TO BLOCK THEM WITH THE SILICATE GLASS. THE REFRACTORY JOINT MAY BE OBTAINED FROM ALUMINA CEMENT.
