graphite crucible

Select water-cooled copper mold and graphite crucible as the reaction vessel, and set different welding current and duration of preparation.

氩弧熔化时分别选用水冷铜模和石墨坩埚做反应容器，设置不同的焊接电流和持续时间。

The sample in tin leaf clad is put into a graphite crucible with a cap. Firstly, the sample is decomposed by heat at about 660 ℃, and the multiform oxygen in the sample is reserved in tin-lithium alloy by the Li2O form.

将锡箔包裹的试样投入带盖石墨坩埚中，第一步先在脉冲电弧炉中于660℃左右热分解，试样中各种形式的氧以Li2O形式保留在生成的锡锂合金中；

Experiment is divided into two phases, First, at high temperatures using high-titanium slag and graphite crucible wall reaction produce the bonding layer of Ti ( C, N), and investigated the influence of reaction time on Ti ( C, N) formation.

实验分为两个阶段进行。首先在高温下采用高钛渣与石墨坩埚壁反应生成Ti（C，N）粘结层，并考察反应时间对Ti（C，N）生成量的影响。

The utility model relates to a graphite crucible with a cover, which is mainly used for growth technology and primarily adopts a falling crucible method for growth of crystal.

带盖石墨坩埚，主要用于生长技术，主要是采用坩埚下降法生长晶体时。
