Problems solved by technology
[0004] In the traditional process of making quartz ceramic crucibles, fused silica blocks are used as raw materials, and unqualified waste products will also be produced during the production process, and these waste products cannot be reused but can only be discarded, resulting in a waste of resources
[0005] In addition, the inner surface of the traditional quartz ceramic crucible is not smooth enough, it is easy to stick material, it is difficult to clean, and the use cost is high

Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] Such as figure 1 Shown, a kind of manufacture method of quartz ceramic crucible comprises the following steps:
[0026] S1, pulping: add quartz raw material and 0.5-1.5‰ lactic acid of quartz raw material and 2-4‰ polyvinyl alcohol into the ball mill. In this embodiment, the quality of lactic acid is 1‰ of quartz raw material, polyethylene The quality of the alcohol is 3‰ of the quartz raw material, and the lactic acid and polyvinyl alcohol can make the prepared slurry suspended and dispersed, stable and not precipitated.
[0027] Wherein the quartz raw material includes fused quartz block material and fused quartz ceramic blank reclaimed material, the mass ratio of fused quartz block material and fused quartz ceramic blank reclaimed material is 1:4~6, in this embodiment, fused quartz block material and fused quartz ceramic The mass ratio of blank re...

Abstract
The application discloses a manufacturing method of a quartz ceramic crucible. The quartz ceramic crucible is manufactured by taking recycling materials of fused quartz block materials and fused quartz ceramic blanks as raw materials to prepare slurry and by processes of pouring, drying, and sintering. Then, by carrying out thermal treatment of the inner surface of the crucible via a plasma generator, a layer of quartz glass can be formed on the inner surface of fused quartz ceramic to allow the inner surface to be smooth. Therefore, waste products generated in the manufacturing process of the quartz ceramic crucible are reused as raw materials; the cost is saved; and resource reuse is achieved.
Description
technical field [0001] The invention relates to a quartz ceramic crucible, in particular to a manufacturing method of a quartz ceramic crucible. Background technique [0002] Quartz ceramics, also known as fused quartz ceramics, quartz glass ceramics, sintered quartz glass products, sintered fused silica products, are products prepared by using fused quartz or quartz glass as raw materials through a series of ceramic processes such as crushing, forming, and firing. In the early 1960s, it was first successfully developed by the United States and put into mass production. [0003] Quartz ceramics have excellent characteristics such as low cost, high softening temperature under high temperature load, small thermal expansion coefficient, good thermal stability, good chemical corrosion resistance, high dielectricity and high resistance, and can be made into quartz ceramic rollers for glass horizontal tempering furnaces, Ram bricks for float glass kiln, hollow rollers for float g...
