Properties of Silicon Nitride Ceramics

There are two types of silicon nitride (SI3N4), both of which belong to the hexagonal crystal system. Both are three-dimensional spatial networks composed of tetrahedrons sharing vertices. There is only a difference in symmetry (α phase is relatively symmetrical), but there is no distinction between high and low temperature phases. The crystalline phase is the […]

Application of Zirconia Ceramics

1. Zirconia refractory (1) Zirconia crucible The melting point of zirconia is as high as 2700℃. Even if it is heated to more than 1900℃, it will not react with molten aluminum, iron, nickel, platinum and other metals, silicates and acid slag, so the crucible made of zirconia material can be successful Locally smelt platinum, […]

The preparation method of zirconia powder

1. Co-precipitation method The co-precipitation method is currently the most commonly used method for preparing nano-zirconia due to its simple operation, easy control of the reaction process, and low cost. The specific process of this method is: adding some stabilizers (such as Y(NO3)3) and dispersing agents (such as PEG2000, etc.) to make soluble zirconium salts […]

Application and precautions of various ceramic crucibles

As an important part of chemical equipment, crucible is a container for melting and refining metal liquid and heating solid-liquid reaction, which is the basis for the smooth progress of chemical reaction. Crucibles were originally made of clay, and one of the earliest uses of platinum was to make crucibles. With the development of manufacturing […]

Features and uses of different types of crucibles

Crucibles are specialized containers for melting metallic materials at very high temperatures. The molten material is cast into new objects or used to make new alloys (different metals combined in specific proportions). Since crucibles are used to melt materials at high temperatures, the material used to make the crucible must have a higher melting point […]
