This article describes a method for manufacturing silicon nitride ceramic micro-components, which combines reaction sintering with micro-machining of porous silicon pre-sintered bodies, and is relatively simple. It is well suited for producing complex-shaped silicon nitride ceramic micro-components because it combines the machinability of a pre-sintered body made of silicon powder with the near-net size molding capabilities of silicon nitride reaction sintering.

The differences in grinding force, specific grinding energy, surface roughness, and surface chipping size of micro-structure grinding wheels on alumina, aluminum nitride, zirconia, and silicon nitride ceramic materials are investigated in this article in order to gain a deeper understanding of the influence of grinding wheel's surface state and ceramic material difference on grinding performance.

The sintering temperature of alumina ceramics is relatively high, however exceedingly high temperatures will cause problems with the product's performance and the manufacturing process. As a result, it is crucial to lower the sintering temperature of alumina ceramics, which can decrease energy consumption, shorten the fire cycle, reduce kiln and kiln furniture loss, and therefore lower production costs.

Ceramics are susceptible to generate defects during production process, and their forming process is influenced by numerous factors. Thus, this article analyzes the factors affecting the ceramic forming process.

The manufacture of alumina ceramics inevitably generates some wastes, and the total value after direct scrapping is still high. Currently,  production wastes of  alumina ceramics are mostly recycled by refractory manufacturers with a low utilization rate. The current recycling methods are complicated and the recycled alumina ceramics have poor performance. In order to overcome the shortcomings of the existing technology, this article describes a method to recycle alumina ceramic waste that is simple and efficient, and can obtain alumina ceramics with high performance.

One of the primary factors affecting the dependability of silicon nitride ceramics is oxidation and the consequent cracks on the surface of products, the decline in grain boundary strength, and the increase in wear rate. Increasing the oxidation resistance of silicon nitride ceramics is beneficial for prolonging their service life, enhancing their dependability and applications in various fields.   Therefore, t his article presents a surface modification method to improve the high temperature oxidation resistance of silicon nitride ceramics based on the oxidation rate control mechanism of Si3N4 ceramics, which has the advantages of strong adaptability, simplicity, low cost and good reliability.

The article introduces a kind of black zirconia ceramic composite with high strength, high blackness, and high lightproof performance.

Alumina ceramic materials often have sintering shrinkage that ranges from 10% to 25%. Due to the significant shrinkage, it is difficult to achieve the dimensional precision requirements of assembly of components, which necessitates post-processing of products. Mostly deformed products require a lot of processing, and the post-processing of high-hardness alumina ceramic materials is highly difficult and expensive. As a result, this article presents how to reduce sintering shrinkage of alumina ceramic materials.

Aluminum nitride is susceptible to absorbing moisture and hydrolyzing in the atmosphere, resulting in poor adhesion of the thick film on the aluminum nitride ceramic substrate, reducing heat transfer efficiency and causing the substrate to detach in severe cases. Consequently, this article offers a method for improving the adhesion of thick film on aluminum nitride ceramic substrates to fully volatilize the water vapor absorbed by the substrates.
