| 31. | The serrated portion was coated with a mixture of ground glass, manganese dioxide, and potassium chlorate.
|
| 32. | Manganese dioxide is a hard, black crystalline substance.
|
| 33. | Because it was used in glassmaking, manganese dioxide was available for experiments by alchemists, the first chemists.
|
| 34. | For instance, potassium permanganate decomposes at 230 �C to potassium manganate and manganese dioxide, releasing oxygen gas:
|
| 35. | Alternatively oxidation of manganese sulfate with potassium permanganate yields the so-called chemical manganese dioxide ( CMD ).
|
| 36. | Most tantalum capacitors are available as surface-mount devices with a solid manganese dioxide or solid polymer electrolyte.
|
| 37. | The most notable driers are litharge, sugar of lead, patent driers, sulfate of zinc and manganese dioxide.
|
| 38. | Representation of the production flow of tantalum electrolytic capacitors with sintered anode and solid manganese dioxide electrolyte
|
| 39. | Types with solid manganese dioxide electrolyte have served in the past as a " tantalum replacement ".
|
| 40. | The electrolyte used in SAL capacitors is a solid state oxide semiconductor, manganese dioxide ( MnO2 ).
