To distinguish 95 porcelain and talc porcelain,< /span>First of all, you need to understand themDifferences .Then let’s take a look at the differences between these two ceramic materials:< /span>
1. Different densities
95 porcelain The density is 3.7g/cm³, the density of talc porcelain is 3.2g/cm³. Their densities are different,< span style="color: rgb(51, 51, 51); letter-spacing: 0pt; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial ; background-origin: initial; background-clip: initial;">That is to say, under the same volume, 95 porcelain is heavier than talc porcelain. So by comparing the weight, you can tell the difference95 porcelain and talc porcelain.
2. Different raw materials
The main component of 95 porcelain isAluminum oxide (Al2O3), industrial Al2O3 is prepared from bauxite (Al2O3▪3H2O) and diaspore. For Al2O3 with high purity requirements, it is generally prepared by chemical methods.< /span>
There are many isomorphous crystals of Al2O3, more than 10 of which are currently known, and there are mainly three crystal forms, namely γ-Al2O3, β-Al2O3, α -Al2O3. Different structures have different properties, and they are almost completely converted into α-Al2O3 at high temperatures above 1300°C.
Talc porcelain is made from the mineral talc as the main raw material, adding an appropriate amount of clay and BaTi03 and other ingredients through mixing, grinding, shaping and high-temperature sintering. The main crystal phase of talc porcelain is original enstatite, that is, magnesium metasilicate (chemical formula: Mgsio3). It is a kind of low-cost high-frequency structural ceramic with excellent electrical properties and is often used as insulating parts in high-frequency equipment.
3.Different application areas< /span>
95< /span>Alumina ceramics have the advantages of high hardness, good wear resistance, high toughness, low friction coefficient, and good corrosion resistance, so Alumina ceramics are widely used in machine seals,Semiconductor, Photovoltaic equipment, ceramic bearings, automobiles Engine parts, etc.
talc porcelain Its characteristics areMedia loss, cheap and available Used in manufacturing high-frequency insulators, insulating tubes and coil bobbins, etc.
