NaBH^Comes in New Form M e t a l H y d r i d e s now sells sodium b o r o h y d r i d e in w a t e r solution
UODRM n o u o m DHIDI is now available in a new form—a stabilized w .iter solu tion ( S W S ) which lias all t h e reactive properties ot pure i9S'» ) sodium boro hy dride. But it's much cheaper--al most (iO'r U*ss than the pure material. The new product form was devel oped by Metal 11\ drilles which states Hath tluit SWS was put on t h e market to catch the interest of cost sh\ chemi cal processors. SW'S is sold as a caustic solution, contains 12'- sodium hornhy dride by weight. It will sell tor S 1 "> a pound ( in 50-gak drums, about 1 . 1 pounds of X a B H , per gallon) based on pure so dium borohy dride content. Metal l l \ drides v\ ill still sell the pure product at the present juice: $33 a pound in lOOO-lb. lots. This means, adds the coinpaiix. that SW'S will be the lowest cost boiohx dride available commer cially . The trick to the lower priced mate rial is to t a p t h e sodium hornhydriile process stream before drying to the solid 9> Fusion engi neering. Cleveland, for use on auto matic silver brazing production lines. The product contains standard silver brazing allox s v\ ith special silver braz ing fluxes in stable paste form, elimi nates separate application of braze allov and flux, says the company. CI4
