摘要：NOVELTY - Composite binder comprises 0.1-1.5 wt.% sodium carboxymethyl cellulose, 0.1-2 wt.% polyacrylamide, 0.2-3 wt.% sodium silicate and 0.2-4 wt.% lime. USE - The composite binder is useful for powder pellet preparation (claimed) and magnesium oxide pellet useful for preparing fused magnesia. ADVANTAGE - The binder has high strength. The preparation method is simple, avoids use of powder directly into a furnace which causes deterioration and pollution to environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for application of composite binder, comprising adding pellet powder into binder and mixing it evenly, pressing pellet, drying and sintering finished powder pellets, where powder pellets has ranges: phi 20 x 10mm- phi 50 x 32mm, specifically phi 20 \8 10mm, phi 25 x 13mm, phi 30 x 15mm, phi 35 x 17mm, phi 40 x 22mm and phi 50 x 32mm.
