"It is coated with a thick ceramic non-stick coating that is free from PTFE, PFOA and other chemicals found in other plastic coated non-stick inner pots. At the end of cooking, it washes up easily by hand or can be placed in the dishwasher. Ceramic non-stick coatings are very hard wearing but it is recommended to use wooden or silicone tools when stirring the contents to prolong the life of the coating.The inner pot can be used in any of the 6 Qt Instant Pot electric pressure cookers as a replacement for the stainless steel inner pot."
disclaimer: there is one review for the ceramic inner pot that says it doesn’t fit but since it’s shipped and sold by amazon, you can just return it if it really turns out that way. Based on the Q&A section, it doesn’t sound like other people had that problem.
