Bulk Ceramic Fiber Insulation
Ceramic fiber is manufactured from high purity raw material alumina powder, silica sand for the high temperature grades and zircon sand is also used. The ceramic mixture is heated in a high temperature electric furnace and the stream of molten material is drawn into fibers by either spinning or blowing .It is produced by advanced “blown” and “spun” processes .Ceramic fiber bulk shows a high temperature stability ,low weight and heat capacity and an outstanding sound absorption is complemented by their resistance to oxidation and reduction
• Excellent thermal and chemical stability

Q3: What other products does OKorder offer?
A3: We offer a full range of refractory bricks, mortar, cement, ceramic fiber products, and more.
Q4: Where are Ceramic Fiber products used?
A4: Ceramic fiber products have many advantages, including: high temperature stability, lightweight, superior insulation, and ease of application. Fiber products are available in a variety of product forms to solve a range of thermal management application problems across various industries. The main industrial market segments that use ceramic fiber and soluble fiber products are the aluminum, iron, steel, heat treatment, power, incineration, boilers, and glass industries.
Q5: What kind of Ceramic Fiber should I use?
A5: When selecting the fiber type for a particular application, it is important to consider all factors. If the fiber/fabric will not have to support a load at temperature, the lower-cost industrial grade fibers may be appropriate. However, if the fiber will be load bearing at temperature as in ceramic matrix composites, then one of the composite grade fibers would be a better choice. Of course there may be other factors, such as corrosion, chemical resistance, or atmospheric conditions that may require trade-off in the selection process.
Q6: What`s the lead time for my order?
A6: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks, 10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.
Q7: Can you offer Door-to-Door delivery?
A7: Yes, but only for some countries such as U.S., UAE, Saudi Arabia, Iran, and Russia, etc.
Q8: What is the minimum quantity?
A8: There is no minimum order quantity. Depending on the item and processing, there may be a minimum production required, however we can offer a quotation based only on the quantity you need
