Ceramic blankets are made of modern ceramic fibre, which is an insulating material that can withstand very high temperatures. It is light, resistant to thermal-shock (a sudden change in temperature) and has a low thermal conductivity so heat doesn’t transfer or dissipate fast.
A ceramic blanket has a very wide range of applications in in the industrial and commercial sector.
What are the uses of ceramic blanket?
Due to its properties, ceramic blankets are mainly used for industrial manufacturing and production. The form of a blanket makes it suitable for direct exposure to flames. Some common examples of its applications are:
- Casting for mould wrapping
- Insulating thermal reactions
- High temperature filtration
- Insulation for steam and gas turbines
- Furnace door linings and seals
What types of ceramic blankets are available?
There are several types of ceramic blankets being sold in the market and they are made with different kinds of fibres. Each type has a difference in terms of temperature grade (what temperatures it can withstand), thermal conductivity, durability, and many others factors.
Some of the most common types of ceramic blankets available today are:
Zirconia fibres, which have a temperature grade of 2600oF or 1430oC. It has a high tensile strength (durable), low thermal conductivity, and low shrinkage rate.
High purity ceramic fibres, which can withstand temperatures up to 2300oF or 1260oC. It has a low thermal conductivity, good thermal shock resistance, low heat storage, and is also very resistant to corrosion.
Maftec/Polycrystalline Mullite fibres, which have a very high temperature grade of 3000oF or 1650oC. It has a high durability, very low shrinkage, and chemical resistant.
Soluble fibres, which have a temperature grade of 2300oF or 1260oC, and its main characteristic is that it’s a safer type to work with for humans, because it does less damage to human cells
