Refractories for Ceramics & Kilns Industry
Tunnel and shuttle kilns firing ceramic tableware, sanitaryware, tile and technical ceramics demand low thermal-mass IFB linings so the kiln can cycle efficiently with low gas consumption, plus mullite and high-alumina refractories for crowns, walls and cycling roof construction. Kiln furniture — saggars, batts, posts, supports — is itself a refractory product and must survive thousands of cycles without bowing, spalling or contaminating the ware. firebrickssource.com — a Rajkot, Gujarat, India based manufacturer-cum-merchant exporter of refractory bricks — supplies kiln linings, kiln furniture and the full IFB K-23 through K-30 range to ceramic plants worldwide, with light-weight, low-iron grades that improve fuel efficiency and stabilise firing curves.

Pain points in ceramic-kiln refractories
Heat loss from heavy linings
Dense hot-face wastes fuel on every cycle. Solution: K-23 IFB or K-26 IFB hot-face, dense brick only where load demands it.
Roof creep at high T
Sprung-arch and flat-suspended roofs sag under sustained 1400 °C. Solution: mullite and 70% high-alumina with low creep.
Kiln furniture wear
Saggars and batts crack and curl after a few hundred cycles. Solution: cordierite-mullite and pressed mullite saggars with stable phase composition.
