Recent advances in surface preparation of silicon carbide and other wide band gap materials M.
In this contribution we recapitulate the state of the art of silicon carbide and related materials polishing.
The first is the extension of the Siface know-how to other types of SiC surfaces and to other wide band gap materials.
Table. 1: Surface quality obtained on different wide band gap materials.

There are three types of agro-products processing enterprises in the cluster: ①production-oriented enterprises, they mainly take agricultural raw materials as processing target; ②consumer-oriented enterprises, they mainly include agro-industry and supporting relevant industry enterprises; ③decomposition-oriented enterprises, they take waste of agro-products processing as raw material [3].
Fujian has built a large number of warehousing, logistics, storage, packaging materials tin, cardboard, plastic foam to support and improve industrial chain and ensure the development of agro-products processing industry [6].
Through the exchange of material and information, agro-products processing enterprises form symbiotic relationship, it augments the use part of material resources and extend the industrial chain.

It is widely used in many aspects, such as engineering sciences, life sciences and economic management, etc [9.10.11].
When it comes to the machining of materials such as hardened steel 7CrSiMnMoV, ceramic tool or greater hardness of superhard tools are good alternatives.

Investigation of Cobalt-free Cathode Material Ba0.5Sr0.5Fe0.8Cu0.2O3−δ for Micro-tubular SOFC with Asymmetric Structure Anode Xiaozhen Zhanga, Yongqing Wang, Jing Zhang, Qibing Chang, Yuhua Jiang, Jian-er Zhou School of Material Science and Engineering, Jingdezhen Ceramic Institute, Key Laboratory of Jiangxi Universities for Inorganic Membranes, Jiangxi Key Laboratory of Advanced Ceramic Materials, Jingdezhen 333001, P.R.
Therefore, remarkable efforts have recently been made to the development of alternative cathode materials with high electrochemical performance in order to reduce the operating temperature of the SOFCs to an intermediate temperature range (below 800°C).
Recently, a novel cobalt-free perovskite oxide Ba0.5Sr0.5Fe0.8Cu0.2O3−δ (BSFCu) has been reported to be potential cathode materials for intermediate temperature SOFCs with advanced electrochemical properties [10].
