Ceramic fiber is a new type of fibrous refractory material which has lightweight, high temperature resistance, good thermal stability, low thermal conductivity, mechanical shock resistance and other advantages. It has been widely used in many industrial areas.

China is one of the largest ceramic fiber producers in the world. It has a large consumer market. In 2023, the scale of China’s ceramic fiber market reached 6.75 billion Chinese Yuan (about 950 million US dollars), accounting for a larger proportion of the global market. At the same time, the demand for ceramic fiber in China is also growing year by year. The temperature of China’s ceramic fiber is from 1000 ° C to 1430 ° C. Production process of the ceramic fiber is divided into spinning fiber process and blowing fiber process. The diameter of the spinning fiber is thicker than the blowing fiber and the length of the spinning fiber is longer than the blowing fiber, so the tensile strength of the spinning fiber is higher than the blowing fiber.

The spinning production process is the more advanced method than the blown production process. Its production capacity can reach 2-4 times that of the blown process for a single production line. Now the spinning production process has been accepted by majority of enterprises and customers in China. Nearly all new ceramic fiber production lines in China are spinning process lines. Almost all the main thermal insulation projects in China adopt spun ceramic fiber.

Ceramic fiber products in China are diverse including ceramic fiber blanket, ceramic fiber module, ceramic fiber board, ceramic fiber paper, ceramic fiber textiles ( cloth, tape, rope) and other forms. The main application areas of ceramic fiber cover power generation, petrochemical industry, steel, aluminum, ceramics, machinery, metallurgical and other industrial fields.

In recent years, the prices of global energy have been rising, so energy saving has become an important problem. Ceramic fiber can save energy, decrease production cost and reduce environmental pollution, so it has a large demand for it. Now nearly all the refractory material production enterprises in China produce ceramic fiber. With the advancement of industrialization and urbanization, as well as the improvement of the use of clean energy, the application range of ceramic fibers will be further expanded.

There are more than 200 ceramic fiber production manufacturers in China, among which about 100 are relative larger manufacturers.China's total ceramic fiber production capacity has been increasing year by year. The production scale of the blown blanket and its market has been gradually reduced. However, the market competition of the spinning process becomes more and more fierce. This is a great challenge for the ceramic fiber production enterprises. They need to save energy, reduce energy consumption and promote production efficiency. Ceramic fiber can save 10-30% energy than the traditional thermal insulation fire bricks and constables, so its development prospect is very promising.
