NettetLinear change is also known as linear change on reheating or residual linear change. It refers to the irreversible changes of its size (length) after heated to high temperature., expressed in %. A positive value indicates expansion, called reheating linear expansion. A negative value indicates contraction, called reheating linear shrinkage. NettetReheatの 線形変更 %。. Refiring linear change 1500℃*2h,%±0.2. Refiringの 線形変更 1500℃*2h、%±0.2。.
