Recrystallized silicon carbide What are the classifications of recrystallized silicon carbide?
Using high-purity ultrafine silicon carbide as a raw material, silicon carbide is evaporated, condensed, and recrystallized at a high temperature of 2400 degrees and under certain pressure protection. So, what are the classifications of recrystallized silicon carbide?
What are the classifications of recrystallized silicon carbide?
Silicon carbide products vary due to their preparation methods, application fields, and morphology. As one of them, recrystallized silicon carbide is a high-performance material in the ceramic field, especially with high strength, high hardness, and high-temperature resistance. According to its sintering method, recrystallized silicon carbide can be divided into reaction-bonded silicon carbide, pressureless solid-state sintered silicon carbide, liquid-phase sintered silicon carbide, hot-pressed silicon carbide, and recrystallized silicon carbide.
What are the entry barriers in the recrystallized silicon carbide industry?
1. Talent barrier in the recrystallized silicon carbide industry
The silicon carbide recrystallization industry requires professional technical personnel. However, at present, the talent cultivation and training system in China's silicon carbide recrystallization industry is not yet perfect. Most enterprises in the industry have not established a special talent training mechanism, especially lacking technical talents. We are technical talents who can continuously contribute to the development of new products and new processes. Due to the need for a high-quality development team and long-term accumulation of technical personnel, new enterprises lack professional technical talents cultivated through long-term production practice, and the lack of talent is a major obstacle to their development.
2. Recrystallized silicon carbide Industry brand barriers
The establishment of a well-known brand is the result of long-term operation and accumulation by enterprises, and it has established a certain degree of popularity, reputation, and loyalty.
A trustworthy brand requires enterprises to invest a large amount of manpower, material resources, and financial resources. In the recrystallized silicon carbide industry, consumers can choose many brands, and well-known brands have relatively stable target customer groups. For new entrants, the competitive pressure of cultivating brand knowledge, brand names, and brand operations is great. To break through the barriers formed by existing brands in the market, it is necessary to increase investment.
3. Recrystallization of channel barriers in the silicon carbide industry
A perfect terminal marketing network is an important sales method in the recrystallized silicon carbide industry, and the establishment of a marketing network requires huge capital and time costs. In addition, good store resources are the focus of competition among enterprises, and they are often relatively scarce. Compared with new brands, existing brands have higher brand awareness and are easier to obtain good store resources, and have greater bargaining power in sales channel cooperation, which creates channel barriers for new entrants.
How is the performance of recrystallized silicon carbide materials?
Recrystallized silicon carbide It is mainly used as high-temperature kiln equipment and requires high-temperature strength, oxidation resistance, and thermal shock resistance. Therefore, there has been much research on the fracture strength of the material at high temperatures, the change rule of oxidation resistance, and the factors affecting the material's thermal shock resistance. The high-temperature fracture strength of recrystallized silicon carbide is higher than its room-temperature fracture strength.
