A pre-sintered porcelain block for dental restoration; the pre-sintered porcelain block does not contain crystal phases and has a Vickers hardness of 0.5-2 GPa. Due to a hardness which is significantly lower than that of the porcelain block containing a lithium metasilicate crystal phase, the pre-sintered porcelain block may be processed by using dry machining and can simultaneously be processed by using wet machining when being mechanically processed into a dental restoration shape.

Pre-sintered porcelain block for dental restoration, preparation method therefor and application thereof

A rapid sintering system and rapid sintering method, the rapid sintering system comprising: a furnace body () comprising a hearth () and a furnace mouth () that communicate with each other; a lifting device () arranged below the furnace mouth (), comprising a support () and a sample stage (), the sample stage () being disposed on the support (); a temperature acquisition device (), disposed on the sample stage (); a control device (), disposed outside of the hearth (), electrically connected to the lifting device () and the temperature acquisition device () and used to control lifting of the lifting device () according to a temperature acquired by the temperature acquisition device () and a preset sintering condition; and a spacer (), disposed at a first end of the lifting device (), a first spacing being present between the spacer () and the sample stage (), and the furnace mouth () is blocked by the spacer () when the rapid sintering system is in a loading or unloading work state. The rapid sintering method uses the rapid sintering system.

Rapid sintering system and rapid sintering method

Disclosed is a sintering furnace comprising a furnace body and a lifting device, wherein the furnace body comprises a furnace chamber () and a furnace mouth (), the furnace chamber () is connected with the furnace mouth (), wherein the sintering furnace further comprises a sealing member () provided at the lifting device; when the sintering furnace is in a loading or unloading condition, the sealing member () blocks the furnace mouth (). When the sintering furnace is in an unloading condition, the sealing member () can block the furnace mouth (), the furnace chamber () does not contact with the outside directly, thus the temperature in the furnace chamber () will not drop sharply, and the service life of the sintering furnace will be increased.
