Problems solved by technology

The granular trititanium pentoxide must be pre-melted before coating, which greatly affects the efficiency of coating and increases the production cost of coating
At the same time, in the prior art, the granular trititanium pentoxide is easy to introduce impurities during the preparation process, forming a large number of pores, and there are substances with relatively large differences in oxygen content, thereby affecting the purity and quality of the prepared coating layer

Embodiment Construction

[0015] see figure 1 and figure 2 , a titanium crystal sintering mold 100, comprising a forming mold 1, a crucible 2 placed on the forming mold 1 and a cover plate 3; the forming mold 1 has a cavity 11, and the cavity 11 includes a plurality of The forming die hole 111 that is close to setting, and every adjacent two forming die holes 111 are all provided with a breach portion 112; The cross section of described forming die hole 111 is circular, and the diameter D of this forming die hole 111 is 25mm and a height of 11mm. The setting of the notch 112 is used for the flow of the molten liquid between the forming die holes 111 and the cooling to form a solid product, which is convenient for unloading.

[0016] see again figure 1 and figure 2 , the middle part of the crucible 2 bulges upwards to form a boss 21, and a groove 22 is arranged around the inner wall of the crucible 2 and the boss 21; a plurality of small holes 23 are arranged at intervals on the groove 22 , and e...

Abstract

The invention discloses a titanium crystal sintering die comprising a forming die and a crucible arranged on the forming die, wherein the forming die is provided with a cavity, the cavity comprises a plurality of forming die holes clinging to each other, and a gap part is arranged between every two adjacent forming die holes; the middle of the crucible is upheaved to form a boss, and a groove is annularly arranged between the inner wall of the crucible and the boss; the groove is provided with a plurality of small holes at intervals, and each small hole corresponds to one of the forming die holes. The titanium crystal sintering die can be used for preparing sheet Ti3O5 crystals or other sheet titanium crystals; the pre-melting time for the sheet Ti3O5 crystals can be shortened, and even a pre-melting process can be omitted; the sheet Ti3O5 crystals can be directly evaporated, so that the coating time is greatly shortened; moreover, the purity and quality of a coating product prepared from the sheet Ti3O5 crystals are effectively improved.

Description

technical field [0001] The invention specifically relates to a titanium crystal sintering mold. Background technique [0002] Trititanium pentoxide crystal is widely used in optoelectronic device manufacturing. It has been widely recognized in the industry because of its stable vapor deposition process. At present, it has replaced titanium dioxide and has become the main application material in high refractive index film materials in the field of display technology. At present, the titanium pentoxide widely used in the industry is mainly granular crystals, and the conventional specifications are 1-3mm, 3-5mm, etc. However, granular trititanium pentoxide must be pre-melted before coating, which greatly affects the efficiency of coating and increases the production cost of coating. Meanwhile, in the prior art, the granular trititanium pentoxide is easy to introduce impurities during the preparation process, forming a large number of pores, and there are substances with relati...
