Machining instruction for 902 machinable ceramics A. First the customer should: - Machine parts to allow for expansion during firing.
A machined dimension of 0.980" will be 1.000" after
firing. B. Heat treatment 1 - For parts with 1/4¡± or 1/2¡±thickness Protect from any direct flame impingement or direct contact with heating elements.Heat at 200ºF (90ºC) per hour (maximum) until a temp. of 1900ºF - 2000ºF (1035ºC - 1093ºC)is reached. IF part is 1/4¡± in thickness then hold at 1900ºF - 2000ºF (1035ºC - 1093ºC) for 1/2 hourIf parts are 1/2¡± in thickness then hold at this temperature for 1 hour. Furnace must be cooled to below 200ºF (90ºC) prior to removing the parts.for parts 1/2" in thickness (this is very important) C. Heat treatment 2 - Thick parts Protect from any direct flame impingement or direct contact with heating elements.Heat at 200ºF (90ºC) per hour until the furnace is at the temperature listed below Heat up to D. Heat treatment 3 Should be used for difficult parts (can also be used for any part ) Protect from any direct flame impingement or direct contact with
heating elements.
