    Refractory Slab Cordierite Kiln Shelves Yellow High Strength SGS Certification


    1. Introduction

    A simple firing to 1300C (about cone 11 and within the reach of many ordinary kilns) and soaked may produce some crystal development. However firing (actually sintering) at 1400C+ with significant soaking time is needed for the best results. Thermal expansion measuring equipment is needed to determine if your firing is actually developing the crystal matrix or not.
    As noted, a continuous crystal matrix is the object of cordierite creation (not just the presence of the crystals in an otherwise typical ceramic). Notwithstanding this, cordierite powder is available, it is prefired and finely ground. It can be plasticized for forming and bonded during firing (at much lower than normal cordierite creation temperatures) to produce a ceramic that certainly has lower expansion.

    Temperature Rating: If firing mid to high temperature (cone 4-10), kiln shelves that are too thin will sag with time so make sure you purchase the right thickness. The shelves thickness options are ½", 5/8", ¾" and 1". The decision need to take into account the firing temperature and kiln shelve length. For example, if your kiln shelf length is 30" and you fire to cone 6, 1" shelves thickness will be a wise choice.

    3. Application

    Cordierite Kiln shelf is widely used to sinter pottery , ceramic insulator and so on.Using temperature can not be over 1300 ℃


    4. Advancer Benefits:
    • Increased load capacity
    • Easier lifting in and out of kilns due to lighter weight
    • Easier on operators’ hands since all edges and corners are smooth and rounded
    • Less need for full shelves since half shelves remain flat indefinitely
    • Significantly less (if any) scraping, grinding and other time-consuming messy or dusty prep work between firings
    • Reduced firing costs over time
    • Faster firing cycles, if desired
