摘　　要：将试验材料刚玉、碳化硅、焦粉、氧化铝、氧氮化硅(Si_(2)N_(2)O)、广西白泥、树脂等按照适当的比例制得无水炮泥,其中抗氧化剂Si_(2)N_(2)O的添加量为0~3%,研究抗氧化剂Si_(2)N_(2)O加入量变化对材料各温度点性能的影响。结果表明:随抗氧化剂Si_(2)N_(2)O添加量变大,材料的马夏值变大,表明材料塑性变差;材料经300℃升温后,材料的气孔率下降,致密度变好,强度指标也不断优化;材料继续升温到1400℃时,材料的气孔率、体积密度及强度指标变化同300℃时变化规律基本一致;对于热态强度,随抗氧化剂Si_(2)N_(2)O添加量变大,材料的高温抗折强度也不断提高,说明抗氧化剂Si_(2)N_(2)O的添加可以改善材料的抗氧化性能,提高坯体致密度。Anhydrous gun mud was prepared from experimental materials such as corundum,silicon carbide,coke powder,alumina,silicon oxynitride(Si_(2)N_(2)O),Guangxi white mud,resin,etc.in appropriate proportions.The addition amount of antioxidant Si_(2)N_(2)O was 0-3%.The effect of the change in the amount of antioxidant Si_(2)N_(2)O added on the performance of the material at various temperature points was studied.The results indicate that as the amount of antioxidant Si_(2)N_(2)O added increases,the Mach value of material increases,indicating a decrease in plasticity.After heating at 300℃,the porosity of the material decreases,the density improves,and the strength indicators continue to be optimized.When the material continues to heat up to 1400℃,the changes in porosity,bulk density and strength indicators of the material are basically consistent with the changes at 300℃.For the hot strength,as the amount of antioxidant Si_(2)N_(2)O added increases,the hightemperature flexural strength of the material also continuously improves.This indicates that the addition of antioxidant Si_(2)N_(2)O can improve the oxidation resistance of material and increase the density of the green body.
