Embodiment 1

[0046] 30 grams of resin, 100 grams of ceramic powder are mixed with 15 grams of curing agent to form 145 grams of organic ceramic mixture, and the moisture content of ceramic powder is recorded by the aforementioned measurement method of the application to be 0.05%, so that in organic ceramic mixture, ceramic The weight percent of powder is 100(1-0.05%) / 145=68.93%.

[0047] The detection method specifically includes:

[0048] Step S1, mixing 145g of ethanol with 145g of organic ceramic mixture to form a first analyte.

[0049] In step S2, vacuum filtration is used to separate the solid from the liquid in the first analyte to obtain a solid isolate.

[0050] Step S4, measuring the weight 102g of the above-mentioned solid isolate.

[0051] Step S5, using the formula m 1 ×(1-s) calculates the weight of the above ceramic powder as 101.95g.

[0052] Step S6, using the formula (x / m)×100% to calculate the weight percentage of the above-mentioned ceramic powder in the above-menti...

Embodiment 2

[0054] The difference from Example 1 is that in step S1, 145 g of acetone is mixed with 145 g of organic ceramic mixture to form the first analyte. Step S3 is carried out between step S2 and step S3, that is, drying the above-mentioned solid isolate until the weight of the above-mentioned solid isolate does not change, and the drying temperature is 100°C. And the weight of the solid isolate measured in step S4 is 100.5g; the weight of the above-mentioned ceramic powder calculated in step S5 is 100.45g, and the percentage of the above-mentioned ceramic powder in the organic ceramic mixture calculated in step S6 is 69.3%.

Embodiment 3

[0056] 30 grams of resin, 100 grams of ceramic powder are mixed with 15 grams of curing agent to form 145 grams of organic ceramic mixture, and the moisture content of ceramic powder is recorded by the aforementioned measurement method of the application to be 0.05%, so that in organic ceramic mixture, ceramic The weight percent of powder is 100(1-0.05%) / 145=68.93%.

[0057] The detection method specifically includes:

[0058] Step S1, mixing 145 g of ethyl acetate with 145 g of organic ceramic mixture to form a first analyte.

[0059] In step S2, vacuum filtration is used to separate the solid from the liquid in the first analyte to obtain a solid isolate.

[0060] Repeat step S1 to step S2 in sequence for a total of 4 times, the organic solvent in each repeated step S1 is ethyl acetate, and the solid-liquid separation method in step S2 is vacuum filtration.

[0061] Step S3, drying the above-mentioned solid isolate until the weight of the above-mentioned solid isolate does...

Abstract

The application provides a method for detecting the content of ceramic powder in an organic ceramic mixture. The organic ceramic mixture includes ceramic powder and organic matter, and the detection method includes: step S1, using an organic solvent to wet the organic ceramic mixture to form a first analyte, wherein the organic solvent and the organic matter are miscible; step S2, the first analyte The solid and the liquid in are separated, obtain solid isolate; Step S4, measure the weight m of solid isolate 1 ; Step S5, using the formula m 1 ×(1‑s) to calculate the weight of the ceramic powder, where s represents the moisture content of the ceramic powder. The detection method does not need to use high temperature, does not need to consume a large amount of energy, and can accurately measure the content of the ceramic powder in the mixture through simple and convenient operation.

Description

technical field [0001] The present application relates to the field of materials, in particular to a method for detecting the content of ceramic powder in an organic ceramic mixture. Background technique [0002] In the production process of organic ceramic substrates, each process needs to be controlled, including the detection of the content of ceramic powder in the mixture of resin, ceramic powder and curing agent. [0003] At present, the methods for detecting the content of ceramics in the mixture of resin and ceramic powder mainly include burning method and baking method. [0004] Ignition method: Burn the sample to be tested at high temperature (temperature greater than 400°C) until the mass is constant, remove the resin in the sample (resin has a low boiling point, and will burn and carbonize when it is greater than 300°C), and calculate the remaining mass as a percentage of the sample The percentage of the initial mass, and then calculate the percentage of ceramic ...
