Product description
Zirconia fiber is a polycrystalline refractory fiber material composed of pure tetragonal/cubic phase ZrO2 nano-ceramic grains. Its manufacturing process is complex and has high technological content. It uses a high-tech "colloid method" to produce a thickened oxide fiber. Zirconium colloid is spun into fiber embryos, and then transformed into Zr zirconia polycrystalline fibers through processes such as dehydration, drying and medium-high temperature heat treatment and crystallization. The chemical composition is ZrO2+Y2O3≥99.5%, and the classification temperature reaches 2200°C. , melting point reaches 2715℃, fiber diameter is 3-6um, single filament length is 10-150mm, appearance is white, smooth, soft, elastic, like absorbent cotton, due to the high melting point of ZrO2 material itself, no oxidation and other high temperatures The excellent characteristics enable ZrO2 fiber to have a higher service temperature than other refractory fiber varieties (such as alumina fiber, mullite fiber, aluminum silicate fiber, etc.). Fiber cotton can be made into: zirconia fiber board, zirconia fiber felt, zirconia fiber module, zirconia fiber paper, zirconia fiber furnace, zirconia fiber special-shaped parts, etc. The products have high high-temperature chemical properties. Stable, corrosion-resistant, oxidation-resistant, thermal shock-resistant, non-volatile and pollution-free, it is currently the world's top refractory fiber material.
Product features
1. The operating temperature is the highest. The maximum operating temperature is as high as 2200°C, and the complete fiber shape can be maintained even up to 2500°C.
2. Excellent corrosion resistance. The acid and alkali corrosion resistance of ZrO2 is significantly better than that of SiO2 and Al2O3.
3. Not easy to volatilize under high temperature and non-polluting. ZrO2 has the lowest high-temperature vapor pressure among all metal oxides, is chemically inert, is not volatile at high temperatures, and is pollution-free.
Product application
1, as ultra-high temperature thermal insulation protective materials and ceramic matrix composite reinforcement materials, used in key technical fields such as aerospace, national defense, and atomic energy.
2. Used to make ultra-high temperature industrial kilns, ultra-high temperature experimental electric furnaces and other ultra-high temperature heating devices with temperatures above 1500°C to 2200°C, for ceramic sintering, metal smelting, pyrolysis, semiconductor manufacturing, quartz melting, crystal growth, Experimental research and many other industrial and scientific research fields.
3. As a high-temperature filter material and high-temperature reaction catalyst carrier, etc., it is used for filtration and impurity removal of liquids or gases at high temperatures, as well as synthesis or cracking catalysis of high-temperature chemical reactions.

Product description
Ceramic fiber is an amorphous (glassy) lightweight refractory fiber material produced by the melting method. The production process is to add different grades of Al-Si compound raw materials into an electric arc furnace to melt them, and then spin them into fibers with different temperatures. Al-Si ceramic fiber, product classification temperature is 1000℃-1430℃. Ceramic fiber cotton can be made by various forming processes: ceramic fiber blanket, ceramic fiber felt, ceramic fiber board, ceramic fiber module, ceramic fiber paper, ceramic fiber cloth, ceramic fiber rope, ceramic fiber tube, etc. Its products have the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and resistance to mechanical vibration. The products are more durable than traditional insulation bricks and castables. The energy saving of materials can reach 10-30%. Due to the rise in global energy prices in recent years, energy saving has become China's national strategy. Therefore, ceramic fibers have been widely used in machinery, metallurgy, chemical industry, petroleum, ceramics, glass, electronics and other industries. application.
Product features
It has light weight, good thermal insulation, good thermal stability, good chemical stability, easy processing and convenient construction.
Product application
High temperature environment filling sealing and insulation (kiln cars, pipes, kiln doors, etc.), fiber composite materials (such as friction discs, etc.), various industrial furnace linings (hot surface and backing), building fire protection, sound absorption, high temperature filter materials , raw materials for thermal insulation and refractory fiber products for deep processing.
