Until now, there are still many friends who can't distinguish between zirconia ceramics and 99 ceramics, so let Mingrui Ceramics take you in-depth understanding.
Introduction of Zirconia Ceramics:
Zirconia ceramics is a new type of ceramic product. It is manufactured using high-tech technology and has many characteristics. For example, it has high strength and hardness. Compared with alumina ceramics, its quality is better. Reliable, at the same time, the wear resistance of zirconia ceramics is also very good. Everyone knows that ceramic products will inevitably be worn and bumped in daily life. If the quality is not good, it may look very old or it will be broken, but The wear resistance of zirconia ceramics will be very strong. In addition to these, zirconia ceramics have phase transformation toughness and microcrack toughness, so they have high strength and toughness, and are known as "ceramic steel". Among all ceramics, it has the highest fracture toughness. Has excellent room temperature mechanical properties. On this basis, we optimized the zirconia formula and process, and obtained high hardness, high strength and high toughness zirconia ceramics with fine-grained structure. High hardness, high strength and high toughness ensure that zirconia ceramics have incomparable wear resistance than other traditional structural ceramics. Ceramics with fine-grained structure can be processed with very low surface roughness (<0.1um). Therefore, the friction coefficient of the ceramic surface is reduced, thereby reducing the friction force and improving the quality of the wire drawing (the drawn wire is smooth and free of burrs, and it is not easy to break).
Introduction of 99 ceramics:
99 ceramics is an alumina ceramic material with α-Al2O3 as the main crystal. It is a kind of high-temperature structural ceramic material that has been developed relatively early, and the content of Al203 is generally around 75-99.9%. It is usually used to classify the ingredients based on the content of Al203 in the ingredients. If the content of Al203 is around 75%, let everyone call it 75 porcelain, if the content is around 85%, let everyone call it 85 porcelain, if the content is around 95%, let everyone Call it 95 porcelain, if the content is about 99%, let everyone call it 99 porcelain.
α-Al2O3 also belongs to the three-part crystal system, and the unit crystal package is a sharp rhombohedron, and only α-Al2O3 exists in nature, such as natural corundum, ruby, sapphire and other minerals. But industrial 1AL203 is used to prepare bauxite and diaspore, and then pre-fired with various additives, which is the raw material for preparing Al2O3 porcelain.
Application areas of zirconia ceramics:
Zirconia ceramics, namely ZrO2 ceramics, have high melting and boiling points, high hardness, excellent wear resistance, insulators at room temperature, and electrical conductivity at high temperatures. So let people use it widely: 1. Mobile phone 3c electronic field, 2. Smart wearable field, 3. Optical communication field, 4. Jewelry field, 5 Automobile field, 6. Daily life field, 7. Other fields.
Application areas of 99 ceramics:
Generally, Al2O3 ceramics have high mechanical strength and high insulation resistance, and are used as vacuum devices, device ceramics, thick film and thin film circuit substrates, thyristor and solid circuit shells, spark plug insulators, etc. With the advancement of science and technology, new varieties of alumina ceramics are constantly appearing, such as transparent alumina ceramics that are widely used in optics.
Through the above introduction, there is a big difference between zirconia ceramics and 99 ceramics. First, the materials are different, the second is the application field, the third is the content and the composition is different, and the hardness is different, and the zirconia ceramic is better in terms of hardness. One chip. However, both ceramics have their own merits.
