问题
I have a link to my facebook, on my website, which opens in the phone's browser.
I would like it to open in the facebook app by default, if the app is installed.
Is this possible?

In general it may not be possible, check this thread: https://android.stackexchange.com/questions/37549/force-link-to-open-in-app-not-my-default-browser
But if you really want to do it, you can follow the same principle as it is proposed on this URL: Open Facebook page from Android app?
In short, try to build an URL of form: fb://profile/pageID. The point of building such URL is because of IntentFilter defined in Facebook app. I am not sure if it will work, but if there is no Facebook app installed this will probably fail.
That should work when you click on a link in browser. It may depend on a browser though.
