红丹在机械炉内生产，用PbO 炉氧化（通常用巴顿法斜方晶Pbo ）。炉内温度范围470-520 ℃ ，氧化速率取决于氧压与炉温以及进行翅化的原料― 氧化物的表面积。
红丹中Pb304的比例随时间增加而变化。且氧化速度保持稳定不变，70 ％-80 ％红丹，之后会逐渐下降达到所需的Pb304含量，这时过程就会终止，从炉内卸料，再重新装人新的PbO 。
红丹应用在铅酸蓄电池时，应将红丹预先进行碾压研磨，还需要以下两个步骤进行混合。
a . Pb304与正方晶系PbO 进行机械混合；
b ．在当达到25 %Pb304时，停止氧化PbO ，这时的炉钩红丹可以使用。
The red Dan produces in the machine stove and oxidizes with the PbO stove.(usually use inclined square crystal Pbo of Ba Dun Fa)The temperature scope in the stove is 470-520 ℃ , oxidize velocity to be decided by oxygen to press and stove and carry on the surface of the oxide of the raw material ― that the wings turn to accumulate.
The proportion of Pb304 increases but changes with time in the red Dan.And oxidize speed to keep stable constant, 70%-80% red Dan, after will descend to attain gradually need of Pb304 contents, the process will terminate at this time, from the stove inside unload to anticipate, again re- pack person new PbO.
Red Dan application at lead sour storage battery, should carry on red Dan in advance Nian to press to grind and also need two steps to carry on a mixture as follows.
a .Pb304 and square are crystal to fasten PbO to carry on a machine of mixture;
B.while being to attain 25% Pb304s, stop oxidizing PbO, the stove at this time hooks red Dan to make
Use.
