Refractory Materials


Castables are shipped dry and mixed most often with water before installation.  Castable can be poured/pumped like concrete, troweled or installed with a gunnite machine. The base materials of castables include fireclay, high alumina, chrome and insulating aggregates while additives can make the castable more resistant to abrasion and chemical spalling or non-wetting to aluminum.

Ceramic Fiber Products

Ceramic fiber products are characterized by their low heat storage, low thermal conductivity, thermal shock resistance, light weight and corrosion resistance.

Our list of ceramic fiber products include:

  • board
  • blanket
  • paper
  • rope
  • cloth and tape
  • pumpable
  • vacuum formed shapes

Firebrick & Insulating Brick

Onex offers options of insulating brick, alumina brick and fireclay brick. Characteristics of fireclay brick include high refractoriness, strength, low porosity, resistance to spalling and negligible shrinkage. The five types of fireclay brick we offer include:

  • Low-duty
  • Medium-duty
  • Semi-silica
  • High-duty
  • Super-duty


When laying brick, the strength of the masonry relies on the strength of the individual brick and, the manner of which they are laid and the mortar material which is used in the joints. Our refractory mortar materials include heat-setting mortars which require high temperatures to allow the ceramic to set and air-setting mortars which set upon drying without a high heat chamber.

Plastic Refractories

If an emergency economic repair to a monolithic lining in a furnace is needed, Onex offers plastic refractories which can be rammed to any shape or contour with ease. Plastic refractories include fireclay, high-alumina and chrome types which are each beneficial to different operating conditions.
