The present invention discloses a welding material for welding zircon blocks, comprising: zircon particles; titania particles; and optional sintering aids such as SiO2, Y2O3 and Fe2O3. It also descibed a method for making zircon blocks, comprising the following steps: (i) providing multiple zircon components to be joined having surfaces to be joined; (ii) applying a welding material to the surfaces of the multiple zircon components to be joined; and (iii) heating the interface to a temperature of at least 1500 DEG C. |
