摘要
在MgO－CaO－C砖中分别加入3％B4C、BN、ZrB2和A1，在1O00℃，2h、1400℃，2h和1500℃，0.5h下，于空气中进行氧化试验。试验结果表明，B4C是一种非常优异和理想的抗氧化剂。进一步试验还说明，MgO－CaO－C砖中加入1％B4C其抗氧化效果已很明显。
An oxidation test on MgO-CaO-C brick has been carried out at 1000℃, 2h, 1400℃, 1h and 1500℃,0. 5h byadding some (3%) B4C, BN, ZrB2 and Al respectively in the brick. The results show that B4C is an excellent and idealantioxidant. Further experiment also shows that obvious antioxidation result has been achieved by adding 1% B4C inthe brick.
