Abstract : this article is about two series of borate and phosphate comprising seven directions. the experiment result shows that both of the two gl ass antioxidants can reduce apparent porosity ， raise oxidation resistance and th e crushing strenth after fire ， but lower refractoriness under load. phosphate glas s is superior to borate in refractoriness under load. which c an attain over 1600 ; so the phosphate glass is a d esirable antioxidant
