Thermal insulation ceramic zirconiaIt has the lowest thermal conductivity among all metal oxides, so it can be used as thermal insulation products. BelowMingrui CeramicsZirconium oxide processingThe factory will tell you about zirconia insulation ceramics
Pure zirconia is white, and turns yellow or gray when containing impurities. It generally contains HfO2 and is difficult to separate. The world's proven zirconium resources are about 19 million tons, and zirconium oxide is usually produced by purifying zirconium ore.
Pure ZrO2 has three crystal states under normal pressure: monoclinic zirconia, tetragonal zirconia and cubic zirconia. Zirconia thermal insulation ceramics are new ceramics, mainly divided into three types: magnesium-stabilized zirconia ceramics, cerium-stabilized zirconia and yttrium-stabilized zirconia.
Zirconium oxide insulating ceramics have very excellent physical and chemical properties. It has not only become a research hotspot in the field of scientific research, but also has reached a certain level in industrial production. It is widely used and is an important raw material for refractory materials, high-temperature structural materials and electronic materials.
Among various metal oxide ceramic materials, zirconia insulating ceramics have the best high-temperature thermal stability and thermal insulation properties, and are the most Suitable for ceramic coatings and high-temperature refractory products.
Zirconite-based ceramic pigments with zirconia insulating ceramics as the main raw material are important components of high-grade glazes; zirconia’s The thermal conductivity is the lowest among common ceramic materials, and the thermal expansion coefficient is close to that of metal materials, making it an important structural ceramic material; its special crystal structure makes it an important electronic material;
The molding of zirconia insulating ceramics is Dry pressingmolding, isostatic pressing, slip molding, hot die casting, tape casting, injection molding, plastic extrusion molding, colloidal solidification molding, etc. The most widely used one isCeramic injection moldingWith dry pressing molding.
