My company wants to buy hydroxyapatite from a new supplier—will it be the same as what we’ve been using?

There is no single form of hydroxyapatite (HA, or HAp) that is used universally for all applications, so the short answer is no.

But that doesn’t mean that you can’t find a suitable equivalent, or even a better form, based on your intended application. With so many uses now for hydroxyapatite across a wide range of industries, it’s safe to assume that every company has unique needs and requirements that must be met when sourcing a new vendor.
