Since the 1990s, some large ceramic fiber production enterprise groups have made major internal adjustments to enhance their anti risk ability.

The production line with backward production and poor economic benefit shall be shut down. It has also made great adjustments in the product structure, greatly reducing its market share in the international market

Ordinary aluminum silicate fiber products with poor competitiveness have expanded the range of high-purity aluminum silicate fiber, zirconium fiber, chromium fiber, polycrystalline alumina fiber and mullite fiber.

throughput. In addition, polycrystalline alumina fiber, silicon nitride fiber, carbon fiber, silicon carbide fiber and other fibers in some famous fire-resistant.

Fiber production enterprises are put into mass production.
