Silicon Carbonates (SiC) are used as abrasives and refractories due to its heat resistance and hardness. Since free carbon is contained in it during the production process, it is known to adversely affect the strength of sintered products, etc. It is necessary to quantify free carbon content.
The traditional measurement (wet method followed JIS) using the hydrofluoric acid method was dangerous and required three days or more for sample preparation before measurement. Hence, the customer asked if there was any safe ways to measure it in a short time.
Our NEW Gas Collection Mechanism(*) enabled us to analyze free carbon
(*) Patent pending
Comparison of the data with or without a combustion gas collection mechanism
| Collect time | Int. time | Meas. time | |
|---|---|---|---|
Conventional method | 0 | 600 | 600 |
New method | 200 | 40 | 240 |
Free carbon in SiC can be quantitatively analyzed safely in a short time compared with the traditional method using hydrofluoric acid. It shows good performance for samples with slow combustion such as free carbon using HORIBA's unique combustion gas collection mechanism, compared with conventional instruments.
Measurement time is also reduced from 10 min to 6 min, and customers are delighted.
