    1. Product Scientific Research and Structural Integrity

    1.1 Make-up and Crystalline Architecture


    (Alumina Ceramic Baking Dish)

    Alumina ceramic cooking meals are produced from light weight aluminum oxide (Al ₂ O ₃), a polycrystalline ceramic product generally including 90– 99.5% pure alumina, with minor enhancements of silica, magnesia, or clay minerals to aid sintering and control microstructure.

    The primary crystalline stage is alpha-alumina (α-Al ₂ O ₃), which embraces a hexagonal close-packed lattice framework recognized for its phenomenal stability, firmness, and resistance to chemical deterioration.

    During manufacturing, raw alumina powder is formed and discharged at high temperatures (1300– 1600 ° C), promoting densification via solid-state or liquid-phase sintering, leading to a fine-grained, interlocked microstructure.

    This microstructure imparts high mechanical toughness and tightness, with flexural toughness varying from 250 to 400 MPa, far going beyond those of standard porcelain or stoneware.

    The absence of porosity in fully thick alumina ceramics avoids liquid absorption and inhibits microbial growth, making them inherently sanitary and simple to clean.

    Unlike glass or lower-grade ceramics that might include amorphous phases susceptible to thermal shock, high-alumina ceramics show remarkable structural comprehensibility under duplicated home heating and cooling down cycles.
