Electric fused zirconia powder is a high-purity zirconia powder widely used in ceramics, electronics, aerospace, and other fields.
Fused zirconia powder is a kind of high purity zirconia powder, which is widely used in ceramics, electronics, aerospace and other fields. Let's take a look at the production process and advantages of electromelting zirconia powder.
1, raw material mixing: zirconia powder and appropriate amount of additives mixed evenly, additives can choose sodium carbonate, magnesium carbonate and other substances.
2, pressing into blocks: the mixed raw materials are pressed into blocks, the pressure is generally between 100-200MPa.
3, cut into blocks: the raw materials pressed into blocks are cut into blocks of the same size to facilitate subsequent operations.
4, vacuum drying: Put the cut block into the vacuum drying oven for vacuum drying treatment to remove water and other impurities.
5, into the electrode: the vacuum drying treatment of the block into the electrode, and through the current heating, so that it reaches a high temperature state.
6, melting: at high temperatures, raw materials begin to melt, forming liquid zirconia.
7, oxidation: in the molten state, the right amount of oxygen is injected into the electrode, so that the liquid zirconia and oxygen reaction to produce zirconia powder.
8, cooling: the zirconia powder after the reaction is cooled to room temperature, you can get high purity electromelting zirconia powder.
Advantages:
1, produced products of high quality, high purity, uniform particles
2, the production process will not produce any pollutants
3, high production efficiency, low energy consumption
4. The particle size and shape of the product can be controlled according to needs.
