While not as common as steel gage blocks, ceramic gage blocks come with a number of advantages depending on the types of measurements you need them for. Ceramic gage blocks have both a thermal expansion coefficient that is almost zero and a zero phase shift. This makes ceramic gage blocks well suited to measurements that may be influenced by changes in temperature. Any temperature changes within the measurement lab will have a minimal effect on ceramic gage blocks, increasing their reliability and dependability. Additionally, ceramic gage blocks last almost forever. Due to the ceramic material, ceramic gage blocks have a high resistance to corrosion over time. While they are more expensive than steel gage blocks initially, ceramic gage blocks will not fall victim to the test of time. One important limitation of ceramic gage blocks to consider, however, is their risk of damage. While they resist corrosion, dropping a ceramic gage block or hitting it with another object has a chance of cracking, chipping, or damaging the ceramic.
