Kam Tai 600*500*18mm Cordierite kiln shelf & shelves for tunnel kiln
1. Introduction
Cordierite makes the ceramic manufacture of products like catalytic
converters possible. They constantly heat up and cool down quickly
and must not crack because of the shock. These converters get their
thermal shock resistance properties from a bonded matrix of
low-expansion cordierite crystals. These crystals form during
firing between 1300 to 1400C (interestingly, cordierite crystals
have a lesser thermal expansion along one axis than another). Thus,
the better the density of the precursor mix and controlled the
firing the better the properties of the cordierite material are.
While cordierite ceramic vessels could be made (e.g. ovenware), the
material has such a low thermal expansion it is very difficult (or
impossible) to match a glaze (without crazing). Notwithstanding
this, many recipes can be found for cordierite ovenware or
flameware. However these are seldom fired above cone 10 so any
thermal shock resisting behavior they have is attributable to grog
content or open fired matrix rather than to any cordierite
development (which is of course not happening).
2. Characteristics:
Excellent energy savings
Lighter weight and higher load capacity
Excellent distortion resistance at high temperature
Suitable for faster firings with better bearing capacity for hot
and cold extremes
Plain kiln shelf
Plain kiln shelf are the most common type of primary kiln
furniture, usually produced by semi-dry pressing, but can also be
made by pressure-casting. There are extra large kiln shelf , extra
kiln shelf, plain kiln shelf, perforated kiln shelf, grooved kiln
shelf,trapezoid kiln shelf, round kiln shelf and special kiln
shelf.
