AL2O3基板

Hello.
I am from TOSHIBA LIGHTING & TECHNOLOGY CORPORATION.　
We are currently producing products using 96percent pure alumina substrates.
We are looking for a manufacturer of ceramic substrates to use in our products. If you are able to produce in the future, could you please provide us with a quote for mass production?
If you are able to provide a quotation, please reply by email to let us know whether you can provide one.
If we can provide a quotation, I will send you detailed information ,such as the quantity to be used, at a later date.
I am in a hurry, so if possible, please let me know as soon as possible whether or not you can provide a quote.
