本发明公开了一种钼镧合金烧结坯的制备方法及其产品，包括以下步骤：1） 混合料的制备：按一定比例称取钼粉和 LaB₆，接着进行混料，得到混合均匀后 的混合料；2）坯料的制备：将步骤 1）中的混和料后的粉末按照需求进行压制， 得到坯料；3）纯钼烧结制品的制备：将步骤 2）中的坯料放入烧结炉中；在氢 气气氛下按照设定的工艺参数进行烧结成型，得到钼镧合金烧结坯。本发明通 过向 Mo 粉中添加少量 LaB6，混料工艺也比较简单，能够大规模应用。本发明 采用的是氢气气氛烧结，烧结设备需求不高，同时烧结温度最高为 1600 ℃，与 传统动辄 1900 ℃以上的烧结方法相比，能够有效节约能源，减少污染，相对低 温烧结也能保证钼金属制品的晶粒大小不会过大。

The present invention disclosed a preparation method of molybdenum lanthanide alloy sintering billet and its products, including 1) preparation of a mixture: taking molybdenum powder and LaB₆, as a mixture to obtain evenly mixed mixture; 2) preparation of the mixing powder in step 1) is pressed to obtain the billet; 3) preparation of pure molybdenum sintering products: placing the billet in step 2) into the sintering furnace; sintering billet according to the set process parameters in a hydrogen atmosphere. The present invention is also simple by adding a small amount of LaB₆, mixing process to the Mo powder and can be applied on a large scale. The present invention adopts hydrogen atmosphere sintering, the sintering equipment demand is not high, and the sintering temperature is 1600℃, compared with the traditional sintering method of above 1900 ℃, it can effectively save energy, reduce pollution, relatively low temperature sintering can also ensure that the grain size of molybdenum metal products will not be too large.
