Frequently Asked Questions
Due to the thermal expansion properties of the alumina material, heating or cooling too rapidly can cause thermal shock and lead to cracking. To extend the product life, it is recommended to warm up and cool down as slowly as possible, avoiding direct exposure to temperature extremes.
