Ceramic Fiber Cotton
Introduction
NC ceramic fiber cotton is produced by melting the very pure raw materials at high temperature, taking advantage of the spun or blowing method with characteristics of stable chemical performance, resistance to most erosion of physical properties like refractoriness and insulation, keeping the same when meeting with oil, water, or steam. Ceramic fiber blanket/felt/board/paperlcloth/rope, and other ceramic fiber products can be produced in bulk through further processing.
Characteristics
NC ceramic fiber cotton is a kind of insulating material which has these characteristics, such as light-weight, antioxidation, low thermal conductivity, softness,
anti-corrosion, low heat capacity, sound insulation, and so on.
Application
Flling sealing and insulation at high temperatures(kiln car,pipeline,kilndoor,etc.);
Composite material in the fiber industry(friction plate,etc.);
Expansion joint filler material for firebricks and castable;
Filler for short-term insulation;
Thermal insulation filling material for small corners;
Raw materials for further processing.

A vacuum furnace is a high-tech industrial oven used for heat treatment processes, primarily in the manufacturing and processing of metals, ceramics, and other materials. The furnace operates in a controlled vacuum environment, meaning that the air is removed from the chamber, creating a low-pressure atmosphere. This unique condition allows for specific and often superior material properties to be achieved during the heating process. Let’s dive deeper into the purpose of a vacuum furnace and why...
