Embodiment 1

[0036] like figure 1 and figure 2 Shown, the manufacture method of ceramic material, the steps are as follows:

[0037]Step 1: Construct silica fume. The silica fume is constructed by ferroalloy when ferrosilicon and industrial silicon are smelted. A large amount of highly volatile SiO2 and Si gases are produced in the submerged electric furnace. After the gas is discharged, it oxidizes, condenses and precipitates with air rapidly. The obtained silica fume is ground with a grinder, and then passed through a filter screen with a filter hole diameter of 0.106mm and a filter screen with a filter hole diameter of 0.0750mm;

[0038] Put the filter screen silica fume with a filter hole diameter of 0.106mm and the filter screen with a filter hole diameter of 0.0750mm and mix them together according to the weight ratio of 2:1;

[0039] Step 2: Weighing the first ingredient, said weighing the first ingredient is to weigh 18 parts by weight of silica fume, 18 parts by weight of white...

Abstract

The invention relates to a manufacturing method of a ceramic material. The method comprises the steps of evenly mixing silica fume filtered through a filter screen with a pore diameter of each filterhole being 0.106mm and silica fume filtered through a filter screen with a pore diameter of each filter hole being 0.0750mm according to the weight proportion being 2:1; weighing a first ingredient which is prepared from the following components in parts by weight: 18 to 32 parts of silica fume, 18 to 24 parts of white carbon black, 4 to 10 parts of silicate powder, 1 to 3 parts of asbestos powder, 2.2 to 6.8 parts of titanium dioxide powder, and 1 to 3 parts of ruby powder with the powder diameter being 0.0450mm. By combining the manufacturing method, the defects of poor high temperature resistance and overlarge heat flux existed in a manufacturing method of the ceramic material in the prior art are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a method for manufacturing ceramic materials. Background technique [0002] Traditional ceramic varistors have been widely used in the production of electronic components, mainly for current limiting protection devices, but high potential gradients will cause flashover or bursting of zinc oxide varistors, seriously affecting the use of devices Life expectancy brings hidden dangers to safety, so it is necessary to apply an insulating coating. The current insulating coating materials have poor aging resistance, low insulation resistance, or require secondary firing. The process is very cumbersome, and the materials contain toxic substances. It will cause adverse effects, so it is very important to study a method of manufacturing a ceramic material that is non-toxic, has excellent aging resistance, high insulation resistance, and does not require secondary firing. [0003] So jus...
