    Fire Ceramics Cordierite Kiln Shelves Lightweight Complex Shapes 500 * 450 * 15mm

    China quality refractory Cordierite kiln shelf 500*450*15mm for fire ceramics


    1. Introduction

    Cordierite ceramics are well known for their low thermal expansion and refractory character. Although cordierite is available as a powder, when we use the term we are generally talking about ceramic that went into the kiln as ordinary composite of ceramic powders but emerges as a cordierite crystalline matrix (grown by the firing process tuned to its needs).
    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.
    Extruded kiln shelf
    Extruded kiln shelf have holes running the length of the cross section and are manufactured using high pressure vacuum extrusion. They are used mainly in the sanitary ware and glass panel industries.


    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.
