Abstract
The invention belongs to the technical field of fire-resisting materials and discloses an adamantine spar and mullite composite material sagger and a method for manufacturing the sagger. The sagger comprises the following raw materials which are electric smelting white adamantine spar, electric smelting mullite, red pillar stone, sillimanite, a-aluminium oxide, silicon dioxide micro powder and kaoline. The sagger is formed by undergoing manufacturing with a mold, mixing of blanks, forming and shaping of a green body, drying and high-temperature burning. A finished product needs to further undergo mechanical precision grinding before being put into a storage. The manufactured sagger is mainly applied to containing of an electronic element half blank in the process of producing the electronic element. In the high-temperature burning process, stable electric performances are maintained. Compared with an original 95 porcelain sagger, good anti-thermal-shock performance and erosion-resisting performance are achieved, the electric performances of the electronic element are further improved and the service life of the sagger is prolonged from two months to six months. The aluminum oxide content of the sagger is low and the manufacturing technology is changed, and thus, manufacturing cost of the sagger is much lower than that of the 95 porcelain sagger. Thus, the manufactured sagger is generally recognized by electronic element manufacturers and replaces the original 95 porcelain sagger step by step.
