CEMENT, ALUNDUM REFRACTORY, for use in repairing muffles, cores, electric furnaces, and in 

 general wherever a refractory cement of high thermal conductivity is desirable. Used exten- 

 sively for covering resistance wire in electric, furnaces. When mixed with water to make a 

 thick paste it is ready for use. Furnished in three mixtures, RA 162 for general work, RA 355 

 where a fine grained cement is required, and RA 305, for use where a cement with a vitrifying 

 point of 500 C. is needed. Unless specified when ordering, mixture RA 162 will be furnished.
