紅丹在機械爐內(nèi)生產(chǎn)，用PbO 爐氧化（通常用巴頓法斜方晶Pbo ）。爐內(nèi)溫度范圍470-520 ℃ ，氧化速率取決于氧壓與爐溫以及進行翅化的原料― 氧化物的表面積。
紅丹中Pb₃0₄的比例隨時間增加而變化。且氧化速度保持穩(wěn)定不變，70 ％-80 ％紅丹，之后會逐漸下降達到所需的Pb₃0₄含量，這時過程就會終止，從爐內(nèi)卸料，再重新裝人新的PbO 。
紅丹應用在鉛酸蓄電池時，應將紅丹預先進行碾壓研磨，還需要以下兩個步驟進行混合。
a . Pb₃0₄與正方晶系PbO 進行機械混合；
b ．在當達到25 %Pb₃0₄時，停止氧化PbO ，這時的爐鉤紅丹可以使用。

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.
