There are
two types
of firebrick: hardbrick and softbrick. Hardbricks are very dense and durable and used for their structural qualities. They can be found most often as the main building component of large kilns, chimneys, fireboxes and burner ports—any- where around direct flame.

What material kind refractory bricks are?
A fire brick, firebrick, or refractory is
a block of ceramic material
used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy efficiency.
Which is a basic refractory?
Basic refractories are used in
areas where slags and atmosphere are basic
. They are stable to alkaline materials but can react to acids. The main raw materials belong to the RO group, of which magnesia (MgO) is a common example. Other examples include dolomite and chrome-magnesia.
How refractories are classified?
Refractories are classified according to
their physical form
. These are the shaped and unshaped refractories. The shaped is commonly known as refractory bricks and the unshaped as monolithic refractories. … Brick shapes are usually divided into two types (i) standard shapes and (ii) special shapes.
What can I use instead of fire bricks?
- Ankar Sandstone. A sandstone type, ankar, is material which comes from a volcano. …
- Red Clay Bricks. Simple red clay bricks can be utilized as another option in place of firebrick. …
- Refractory Concrete. Refractory concrete is another choice for heat retention. …
- Soapstone.
Why is firebrick so expensive?
These brick have
very high alumina content
, get very hot (1500F and up) and are designed for continual high-heat applications, such as furnaces. They are expensive, and will get too hot for some of your oven uses, such as baking bread and roasting.
What is the best material for fire bricks?
The best material to build a blacksmith forge fire brick is

What is brick earth in civil engineering?
Brick earth should contain
about 50 to % of silica
. It is responsible for preventing cracking, shrinking and warping of raw bricks. It also affects the durability of bricks. If present in excess, then it destroys the cohesion between particles and the brick becomes brittle.
What is a good refractory?
A good refractory material should have the following properties: 1.
It should be able to withstand high temperatures generated in the furnace
. … Its contraction and expansion due to the inevitable temperature variation should be minimum possible.
What is a refractory patient?
(reh-FRAK-tor-ee) In medicine,
describes a disease or condition that does not respond to treatment
.
What are refractory services?
Refractory services
manufacture, install and repair refractory shapes and monolithic
refractories. Refractory shapes are hard, heat resistant materials that are suitable for applications which require high temperature strength, wear resistance, electrical or thermal insulation, or other specialized characteristics.
