Frequently Asked Questions
What are Refractory Materials?+
Refractory Materials are products that keep their strength and chemical stability at high temperature and line furnaces, kilns, ladles and reactors, supplied either as shaped bricks or as unshaped castables and mortars based on alumina, silica, magnesia or silicon carbide.

What are Refractory Materials used for?+
Their main applications are iron and steel furnace and ladle linings, cement and lime kilns, glass tanks, non-ferrous metal furnaces, boilers and incinerators and foundry equipment. RAVMENT supplies Refractory Materials in bulk and exports them worldwide — request a quote.
What is the difference between shaped and unshaped (monolithic) refractories?+
Shaped refractories are pre-formed bricks and blocks laid like masonry, which suits large regular linings. Unshaped (monolithic) refractories — castables, ramming and gunning mixes and mortars — are installed on site, take any geometry and make repairs faster. Service temperature and chemical attack decide which class and which base oxide are appropriate. RAVMENT supplies Refractory Materials in bulk and exports them worldwide — request a quote.
